Ok... I'll try to do that this weekend.
Thanks man... you da bomb. Or maybe make it pop up and ask you if you're sure you want to mark all messages read... anything would be better than having to dig through peoples message history to find the last 10 messages posted.
One of the changes I want to eventually make to the code is to be able to set an arbitrary lastread date. So say if you wanted to mark everything within the past week as new, you could.
