hangin' on the forum?

 From:  DannyT (DANTAS)
Yeah, it happens to me once in awhile during peak hour traffic :) , like when there are few topics going on and people are posting at the same time I find I get 'hang', but I let it go and it eventually sends, sometimes I stop it and send it 5 or 10 minutes later and it's instant.

That's my guess.
