Mailing list/message board combination?

Is there something available that acts as both a message board and mailing list where: - users can interact via email online (mailing list) with all message being stored in message board format for web browsing - users can reply and create new discussions via the web message board which also sends to the mailing list Users could subscribe/unsubscribe to lists like normal mailing lists. A PHP/MYSQL solution would be great, or maybe a front-end that ties into qmail/majordomo, something like that. I found http://mailgust.phpoutsourcing.com/ but it's just getting underway. Does anyone know of another application like this? __________________________________________________ Do you Yahoo!? Yahoo! Web Hosting - establish your business online http://webhosting.yahoo.com
