[OUTDATED] Function
For the newbies, including me, it'd be easy when you are able to see, that this thread is inacitve right away by adding an "[OUTDATED]" tag infront of it when there hasn't been a post in... let's say... 6 weeks?
Short:
When a thread hasn't been replied to within 6 weeks it will be tagged with [OUTDATED].
Would this be a good idea? Don't know.

It just came to me, because I apperantly "refreshed" very old threads.
