The email didn't work, because I only get IM emails when I'm offline. What I wanted was a way to capture the text from an IM without having to copy and paste it from chat when i was actually in SL. I resolved this myself by finding the chat log, copying it to my server, then parsing out the data with .NET... "Look, Ma, no LSL needed!" ... this wont work for anybody but me, so it isn't marketable, but it's good to know.
Thanks for your help.
