You might want to take a visit to the Kilgore College Choir blogs and welcome them into the blogging world. The director just started a couple. (he had posted a question about blogs/forums on the ACDA website)
I also found one that started one after the ACDA LA convention . . . can't remember where i saw it, though. (found it!)
Also saw one here, but it is more political in nature than musical! And the director seems to hate republicans and our president. I refrained from commenting on the posts although it was difficult!
