Thing is though, when people post bike pics thread, theyre constantly bumped to the top of an otherwise useful forum with posts such as 'cool', 'nice bike m8', 'i dont like the bars' etc.. (something which can be posted in the gallery.. although saying that it is a bit shit at the moment but it'll have to do for the meantime)
Leaving the post there and just closing the thread means (as mark said) they can still get their pics from there, secondly leaves a reminder to other users that bike pics should go in the bike pics thread.. and thirdly it stops us getting PMs going 'wheres my thread gone'..
