Forum members will NOT tolerate any threads that follow the lines of "Hey, why is the______thread back?"
If the thread is back it could be for a few reasons:
1) A member posted to it.
2) A moderator revived it from the dead threads area
3) The original poster revived it.
All three actions do NOT have to be questioned. Simply respect the judgement of these persons, and let it go.
And IF a thread was moved to a different forum by a moderator, it would still be listed on the original forum, with an arrow next to it, indicating a move.
Once again, do NOT start useless threads asking why threads are recycled.
Just a little joke...
