Okay, it looks like the mass email *did* work... twice!
Sorry for everyone receiving double emails... somthing's wrong with the board's email function. When I sent the mail, it came back with a "General Error"... but it looks like some people are getting the emails.
Man, I look like a tool.

I can't get my board's email to work right, and I don't even know the name of the place we're meeting at! hehehe
