I Purchased 100(.25% Cut) Steem off of Poliniex and was not sure how to convert that to my account but I learned from the account above it was extremely simple.

1. Purchase steem once it is in your Deposits & Withdrawals Tab you simply hit withdraw.
   Above screenshotted is how the information should be arranged

2. Set Up Withdraw From Poloniex
   Address: Your Steemit Username "Like So"
   Memo: Click on wallet, permissions it is the last address and should begin with "STM"
   Amount: How much you wish to deposit onto your Steemit.
   -Check for email to accept/confirm withdraw.

3. Once It Hits Your Steemit account, Click Steem Then Power Up & Voilà
