It depends. Were you not visiting TFP for about a month or two? Fairly recently, TFP had to reset and everyone, EVERYONE lost their accounts/posts/everything. So we all started back at one. It may be the case that you were there before the reset, but have did not make it back after the reset.
If that didn't make any sense, and I'm sure it didn't because I barely understood that, let me try to rephrase it
1) TFP reseted itself. That took about a week or two.
2) Everyone had to set up new accounts, including the mods and admins. Nothing was saved.
Thats about it
