Some people are creating their original username -- but the are then sifting as normal but with 0 videos and 0 history.

The problem is when your acct is re-connected to your former self, the new activity is lost in limbo. (Technically, you can sneak in a few extra votes this way)

When your old acct is re-connected with your username, the temporary acct (with zero videos) is renamed to "used-to-be-Username". It's not clear if Lucky will eventually destroy all of these accts.

So just post a msg in the main SiftTalk if you still have zero videos and no history yet.
