I would do another poll. We have several vent/ts out there for LOL alone. Its very very hard to get everyone onto one. People have their own where they have their private rooms and server admin, ect. I love the idea of having one but from past experience it seems that people who are in the community don't want to give up that "control" factor. If the people actively using this forum, which for the most part are LOLers, aren't going to be on it while online gaming then its a waste of money for you(or OKGamers whoever is paying for it).
If there aren't a lot of OKGamers on it then I won't be logging into the server on a frequent basis. The poll should simply state, "Yes, I will use OKGamers voice server on a consistent basis" and "No I will not use OKGamers voice server on a consistent basis"
I think the results will speak for themselves and you'll end up saving some money. Even though I wish I was wrong as I'd love one central voice server but its just highly unlikely from my past experiences.
