ok how much i think this is a great idea you all have to remember we have kids in the game. aka Squeeker's. 
if you put yall's vox in here and a squeeker joins your channel and you dont want him to be there what do you do then ? 
1) If they are that bad, it's very very unlikely they have a BB account.
2) "If" they get on channel simply ask the to leave
3) If step 2 fails, proceed to Squelch
4) If the said person continues to annoy you for more than a day, use report and or contact HTC.
The end
