...and while you're at it I've got another suggestion.
Since the default for creating / replying to a thread is to subscribe to it, it would be nice to have a way to do a "bulk unsubscribe" on the My Subscriptions page. I just got done cleaning up my list (as well as I could without being able to touch the "private" ones) and it took quite a bit longer than it should have since the telerik site isn't exactly blazing fast. I'll never complain about slow site speeds since there are a zillion factors - most of which are out of the hands of telerik, but still there are steps that could be taken to avoid constant postbacks and page-loads.
So, when you make the change for the "private" threads - go ahead and throw a checkbox column on the My Subscriptions page that will allow us to delete a whole bunch of subscriptions with one click....that would be just super! Thanks and you guys rock!
