i know you're a bit bitter about the lack of a PM feature in blahblah, but what about this:
every member has a nice "contact me" link, which will lead you to a page with various ways to contact the member. this will still mean that blahblah won't keep a pm inbox for you, *but* it will still be really easy as to send messages to other members.
hmm... or what about having a thread for every member that anyone might send something too.
so basically you don't have pms, but anyone can "write you" via "your thread".
this would make messages sent to you visible to all other members, but at least we'd have an inbox for you.
what do you use PMs for most of the time?
