Hi! I havn't been using oQueue for very long, but something I would really like to see is being able to sort premade groups by whether or not they are using a chat service. 
I think a lot of people strongly prefer either one or the other and myself personally wouldn't consider running without using ventrilo.

I agree! This would be a great filter/requirement when creating a group. 

"Voice Required" should be right in there with ilvl, res, rating. 

Sweet! Looks like this has been added :D Thanks tiny!
