Thread: Silly question or good idea?

I am throwing this in as a suggestion, don't know if its's possible or not but never will know without asking.

I have seen quite a few potentially interesting threads recently and gone to them only to discover that they are older (1-5 years) that have had a recent post to revive them, often by someone who is not aware of their age.

Is it possible, cost effective, etc to scan the starting date for a thread, and change the display colour for the originator and origination date (i.e line below thread title) in the thread list to indicate that the thread started recently (normal), 6-12months ago (say orange) or more than 12 months ago (say red).

I try to manually scan for very old threads before opening threads, but sometimes forget. From the number of old threads being reactivated, I might not be the only one suffering brain fade.

Thanks
