I would like to be able to do a query against a members messages and generally just read through a member's message history. It appears to me that member message lists are truncated.
Go to the person's profile, click the Postings tab. Scroll to the bottom and choose the Fibd All Contact link.
When I'm looking for posts, I just click on the avatar/user and get a popup. In that popup, if you look next to "Messages" there will be a clickable number beside it.
