Wow. Sorry to hear about the ups and downs, WLuke.. Take your time. We're all living without this modification as it is - when you finish, you finish.
Otherwise, just to let you know, I'm interested in this. I just moved
www.80sxchange.com to a new host and it's not even ready yet. As soon as my UBB goes up and is functioning, I will be converting to vBulletin 2.03 - so yes, I am very interested in this feature you are working on...
