Thank you all.
As a moderator, I need all those things listed that it seems Mark is working on vis-¨¢-vis searching the message archive by author/ email address etc ( with actual links to the messages) or simply search results like the normal search function brings up.
As a member of groups that I am not an admin on - it would indeed be nice to have a way to find my own posts. Maybe it'll just be via the advanced search option/ search by author when/if that gets fixed. Or as Shal suggests maybe an activity history tab/log? Maybe a listing of "MY POSTS" in one's profile? Visible to the member only?
