Topic: Mailing users from within the forum
Right now, when a user chooses to mail another user from v 1.2.5 the sending users email address is revealed to the recipient. It seems like it would be a relatively easy thing to use the same email address that's used for sending out forum subscriptions for sending user generated emails. Those emails would then have a link in them pointing back to the senders profile page on the forum (just like in the email that's generated for admins when a new user registers).
That way users can communicate with each other privately, without dedicating database storage to a private message system and without revealing their email address unless they choose to.
Again, this is something that I can probably make work, but it seems like a basic privacy consideration that many forum operators would appreciate.
