OMG mIRC!!! holy poop. digging up my past here.
man I remember hopping from server to server trying to leech files off before the days of file sharing.
wow, those were the days, its all just too easy now lol.
Out of curiocity though, why not use a medium thats a little more available to everyone?
There are apps out there for phones like Kik messenger where you can have as many people as you want, come and go, its all free etc.
everyone's got a phone right? Hell even Discord is becoming a contender in this feild.
It supports everything. Text chat, voice chat, different rooms, can be accessed on any platform, through apps or even web browser access. etc. of course its all free.
