Re: Mass email function
I’m a member of a few forums that send out announcements.
Some hosts will limit the number of emails you can send at once though. Dreamhost, for instance, has a limit of 100 per hour (one of the many reasons I’ll be leaving them soon).
It would be overkill for some sites, but it would be nice to have a plugin for PHPList that would share a WordPress and/or bbPress user database; one that would allow user control of mailing list preferences in the WordPress or bbPress profile.
