No matter how great, there is no reason to bump threads from 2009
Do you intend to turn the whole site upside down?
In fact we are asked not to in the announcement thread at the top of the page:
Please try not to bump too many older threads or threads from the back of the forum. Doing so puts them on the first page. If stacks of old threads get bumped then the front page becomes full of old threads and pushes the new content submitted by users down. This can make it seem to regular members that there are not any new threads for them to view. So please limit bumping of old threads :)
Thanks, Kelly
