Many thanks trafix - excellent work, thank you.
Just to push the envelope a little further

How might I be able to include a start & end time? In other words, let's say I wanted to move all messages from a specific year, so for example....January 1st, 2002 to December 31st, 2002....into an archive sub-forum called 2002 Archives?
That way, at the end of each year, I'd be able to archive it's messages and start over from scratch with a 'clean' set of live forums for the new year.
Just an idea. Thanks.
