Ventrillo!
There is no way to "lock" the tuned channels, or Password protect them, etc. I have often wished there was.
As squadrons in AH have gotten larger, it gets increasingly difficult to manage communications.
Either you have some canadian burping in your ear, and saying "EH" all the time.
Or you can't directly hear and talk to squad mates. Can't find em, wing up, etc. Because they are technically in another squadron.
The heart of the matter is the 32 person limit per squadron, and thats not going to change.
Ventrillo is ok if your JUST useing ventrillo, if you fly with it every day or 2. Then eventually you learn the keys, and get things sorted out. However our squads big thing is FSO, and half the problem is half of us forget what we were doing with ventrillo in between frames. I don't know what the answer is. Hopefully someday when the "Lord and Master" the "Great and Powerful" "Lord Hitech" has a minute or 6 he'll take pity on us poor mortals and find us a better solution. (Gets out of his chair, turns toward Texas, kneels, bows 16 times saying the 16 holy words.)
PLEASE oh great and powerfull HiTech we beeseecheth thee.
Truly we are dust under thy feet, but that very dust doth support thee.
Thou art the Alpha and the Omega but we art stucketh in the middle.
HTC hear our plea.
