This is EXACTLY what we need in this product to push it closer to the top. One good (free!) example of this functionality is
www.egroups.com now bought by Yahoo!
Egroups doesn't allow me much control and I want to move to another solution, but the lack of this functionality is keeping me from making the move. If this is going to be done, I'd love to know the ETA so I can figure it into my timing.
Thanks...product looks great and I know it will smoke with PHP and MySQL.
