Skype just partnered up with HighSpeedConferencing.com. You can call into conferences set up by HSC for free using a special number in Skype, you won't be charged any SkypeOut credits.
The best thing about HSC is that it has a web interface with moderation. This will solve the problem of constant faggotry being executed within the voice bridge without having to move to other extensions.
On top of that, HSC has numbers in the US, UK, Germany, and France. I know there are a few people in the UK that can't even call the voice bridge because it's way long distance.
This is just a suggestion by the way.
