Introduction requests/responses never get ACKed
It looks like that in private conversations all messages except actual private messages, never get ACKed. There is only ever one checkbox for forum/blog and introduction messages even if the message has been delivered on the other end. Leaving and re-entering the conversation doesn't help.
