Is there anybody who can solve my problem ?

we are 30 odd students who want to discuss online without getting disturbed and all of us are scattered over India.Normal chat rooms do not give the security of privacy even if they do I am not aware of that.
I have seen a button of create room in yahoo messenger. but I am unable to proceed.Is there any software or any site or ant service if paid or free.
Kindly plz let me know.in detail

if you are using yahoo messenger then why don't use the conference feature? thats the easiest way i suppose.
