Does this app support a 500 + member discussion list? looking for a yahoo type group list where all members can respond to eachother or the group as a whole. with attachments., yes I have a web host running linux, perl, php and access to them
Also ability to "turn Off " posting for any time frame, tried the demo but I didnt see any provisions for the dicussion list part. If so, how about a try before we buy, already have invested in those advertized that claim they do
needed badly

If you are looking for a discussion list, why not just use majordomo, it is free.
