Hah that preview thingy is funny, yeah gotta see if it can be reasonably modded out.
As for the thank yous, are you guys sure you aren't just getting thanked for some post you did waay back?
During the previous update, when we went to SMF 2.0, we had to reset the names shown in thank you-posts, but the data for which posts got thanked as well as the total number are still there, just not all the name info.
