This at tagging thing is sorta dumb anyway. Its a bandaid on the lack of reasonable user notification add/remove controls. I made the mistake a few months back

This at tagging thing is sorta dumb anyway. Its a bandaid on the lack of reasonable user notification add/remove controls. I made the mistake a few months back of saying something like "and if you use our @corp.com email address the internal filter does X", and the stupid "chat" program proceeded to ignore the .com part and notify the entire company of a small tech discussion on my team. Cute.
