Destroy? No. Rename? No, it's one of the threads that actually works with a official tag. You actually know what you're talking about for Gunbuster and are a constant active participant. If all "official" thread starters did that I wouldn't care, but we had a slew of threads that were started but did not have in-depth knowledge about the subject. They were more of a "super" thread-type in that the starter did it to consolidate the threads but then seldom returned to participate in it later. I have the same opinion as Roy that alot of those threads were created to simply have shock value like the ebay listings with the prefixs "LOOK" or "A MUST HAVE." Happily there are some exceptions to that rule.
My definitions :
Official threads - created by passionate fans who have a real love for the subject and have done a ton of research on it and actively contribute to that thread OR created by admin/mods.
Super/Mega threads - created by fans to consolidate all threads of the subject in question but more as a general free for all. ie the Transformers thread.
