This is the error message I've been getting when I try to send a comment via the SB. I can send comments via profiles and http://subeta.net/users/comments/(insert username here) on the comments page, but not through the SB feature.

Also, alerts have been taken away from events when someone joins a forum group. Admins don't know there's a new person or people and they don't always remember to check and it makes the new person/people wonder what's going on and can make people even upset. Please bring notifications back!
