Backup your private keys!!!
If you are new to Steemit and/or the idea of blockchains, crypto currencies, etc..., you may not know that in addition to your Steemit.com password that you set when you made your account, you also have a set of private keys that you can use to recover the funds from your Steem wallet in the unfortunate event that Steemit.com is down, or if the website developers decide for any number of reasons to block your account. As stated in the terms of service, you are responsible for storing your private keys in order to maintain control of your wallet and funds. What does this mean for typical users? Just take 5 minutes to follow the steps below to ensure that you have a backup of your keys at least somewhere.
1. While logged in, click on the little profile person button in the upper-right corner.
2. Go to the permissions page.
3. Click 'show' next to each of the four listed keys
4. Save the private keys
Once you click 'show' to reveal your private keys, an option to print the page will appear. If you have a 'dumb' printer, this is a reasonable option to keep a paper backup of your keys. Otherwise, if you have only small amounts in your wallet, printing to a pdf file is a reasonable decision, although a better decision would be to print to a truecrypt volume for example.
*Note: I've covered up both my private and public keys, mostly because I was paranoid I would accidentally show the wrong ones, but everyone's public keys are available at the links steemit.com/@username/permissions.
