under FAQ from the nav bar (user info), there's an faq for both p3ts and critters.
when you pass the mouse over the options in the userbars it shows random letters below the list of links.
When making a userbar, if you select a random option (display random user info, for example) it displays an error message when you try to view the image (it just goes blank in the preview pane)
The critters sub-forum has not been renamed to p3ts.
From the Arcade button at top of forum, these links end at a 404 page - vbookie, yahtzee, sudoku, quiz, mini-poker.
I think you mentioned that they had been taken out? The links are still there >.<
That's all I found so far...
* Cintaria goes off to find more
[edit]
In the arcade button, the p3ts button still says critters.
