[@Symphoni], [@Ellri], [@GooberGrape], [@ArenaSnow]:

This is definitely something I've wanted to do for some time now.

I've come up with a solution for letting people delete convos (and thus leave the convo and receive no notifications for future activity in that convo), but it's a complex feature that would demand an entire weekend. I'll have to make time for it, I just don't know when that will be. 

I will definitely do it [i]before[/i] I develop any major new features but [i]after[/i] I fix the current bugs that are impacting people today. This is definitely the most important and most requested feature on my plate. :)
