The Basics of Navigation
Your Account Homepage
Diagram 2 - This shows a screenshot of my homepage for illustration
This is your central hub for Steemit. At the top left (A) you will see tabs for the various different feeds such as home, new, hot, trending, promoted and active. Clicking on them will take you to them. On the top right (B) is a magnifying glass which lets you search steemit, next to which is the "Submit a Story" button which is used to make a new post. To the right of this is a symbol of a head which reveals a drop down menu with various quick access options for your account. Finally to the right of this is pictogram of three horizontal lines - this offers links to things like the Steemit Whitepaper.
Directly below all of these you will see your username with your repuation score in brackets. Next, directly below this (C) will be your stats in regards to follower number, post number, and number of people that you follow. Clicking on either "followers" or "followed" numbers will take you to a list of each where you can see them and manage them.
Down below these is a black bar with various tabs on it (D). "Blog" lets you view a list of your posts. "Comments" shows comments you have made on other people's posts. "Replies" shows people's replies to any of your posts, comments or otherwise. Rewards lets you view your author and curation rewards.
You can now set your own avatar. Make sure to use a square image as it will be cut into a circle. You don't need a very large image either as it will only be displayed at about 50 pixels diameter.
The way to set your avatar is to click on the "Settings" button in the upper right corner of your homepage. It is in the black bar next to the "wallet" button:
You will need to use an image host such as SteemImg to first upload the image you wish to use. Insert the image link from your host into the URL box (which will be empty in your case). Once you insert a new image URL the button in the image above will no longer be greyed out and will say "Update". Click on it and you are done.
There are now notifications when you have a new reply to one of your posts, as well as an indicator to tell you when there are new posts in your home feed (from people you follow). Further as you can see in the screenshot above there is also a little indicator which shows when you joined Steemit.
The Wallet Page
Diagram 3 - My Wallet Page for Illustration Purposes
This is accessed by clicking on the "Wallet" tab on right side of the black bar on your homepage (E).
This shows you the amount of Steem, Stem Power and Steem Dollars you have along with your estimated account value (M in next diagram).
It also shows your transaction history at the bottom (H).
Next to each amount for each of your currency types are various drop down menus which are accessed by clicking the disclosure triangles to their right. For Steem you can "transfer" to another account, "power up" (which converts it to Steem Power). "Buy or sell" allows you to sell it on the internal market. Finally the "Deposit" option lets you buy Steem using Bitcoins via the Blocktrades service. There are similar options for Steem Dollars allowing transferring and trading on the internal market and "Convert to Steem" - which converts your SD into Steem internally after a week.
You can also buy Steem or SP using the button (L) which seems to duplicate the functionality mentioned above.
Steem Power only has 2 options - you can "Deposit" using bitcoins in a similar process to that for regular Steem. "Power down" starts the process of converting your SP to Steem weekly over a period of 104 weeks.
Permissions Page (For security reasons I have not shown this)
This is accessed from the wallet page and is next to your wallet in the tabs (K). For Steemit you have 4 different keys with both public and private versions. If you click on the Permissions tab there is an explanation of the role each key serves which I have copied here for your convenience:
Posting: The posting key is used for posting and voting. It should be different from the active and owner keys.
Active: The active key is used to make transfers and place orders in the internal market.
Owner: The owner key is the master key for the account and is required to change the other keys. The private key or password for the owner key should be kept offline as much as possible.
Memo: The memo key is used to create and read memos.
As stated next to the Owner key for maximum security you should only use it when you have to. Therefore if you are logging in just to post then you should use your posting key only to do that. This ensures that if it is stolen or hacked the person who takes it can only post on your account and not actually make any transfers or steal from you.
The final tab on the right (in K). This lets you reset your password and generate a new password.
This is a new feature which was added after my first version of this FAQ. You can transfer either Steem or Steem Dollars to the savings account as a security measure. Funds that are transferred there are subject to a 3 day delay before being moved.
Here is a magnified view of the specific area shown above:
Simply click the disclosure triangle next to the Steem or Steem balance in your wallet to bring up the option to "Transfer to Savings".
