>>Ok, my apologies. I understood your previous post as regarding the negative side of the discussion and that's why you would rather not respond. I agree about the thread drift issues. I guess UT doesn't break threads away to new ones when they start drifting.

Some, after such a potential thread break, would discuss about the initial topic even in the thread break portion which would make it impossible to link back to the original thread. Those are some reasons given as examples.

I have GMail from Google as one of my email accounts and they have a great way of using "labels" on messages. You can add as many labels as you want to an email and then just archive it. I guess it wouldn't be practical, but it would be kind of cool if there was a way to have multiple titles (labels) on threads. There could be the primary one it was created under and sub-level ones if drift occurs. Probably hard to administer though.
