I'm not on a dedicated server but i've never had a problem with sending multiple emails in the bcc field. Also, I believe that the "email users" function has worked periodically but I'm not sure of this. In any case I would greatly appreciate it being put on the bugs forum and being treated as a known issue. This is a very important function for us as we use the forums as classrooms/conference rooms for professional groups and sending them periodic announcements is crucial.

Thanking you in advance,
Dan Hill
