Hey Zoo I am an assistant admin of another msn group and have been searching for a decent group type forum as well.  I didn't like the set up of multiply at all....  But I am a member of a rescue dog board that is hosted by http://www.hyperboards.com/ 

 

It is a free group hosting site that is better then multiply and set up more like a group board.  The only down side is you cannot host your images on there you need to use another free host site for images such as photobucket or imageshack.  Still the set up is 100% better then multiply you might want to check it out.....
