Marieg:
At the top of the quilting board page there are things listed like "Random Topics, Search, Recent Topics and MEMBER LISTING. If you click on Member listing you'll get a list of everyone who is on the board. I think the listing goes by members who have posted the most messages down to those who have posted the least ...so, you can either find the last post your person wrote and see how many messages she's sent and then go back to the member list and got to that area of the list with the number of posts she/he's had. I hope this explanation is clear.
