Ventrilo

Ventrilo is a garbage VoIP. To be honest, who still uses this? This isn't early 2000. Ventrilo is literally a step below TeamSpeak but was a step above Raidcall. It serves a purpose of providing voice chat but with terrible latency. The website looks like it's from 1998 so I can imagine just how the program interface still looks. Yiiiikes.

I use this to play games. RTS (Real time strategy), MMOs (Mass Multiplayer Online), FPS (First Person Shooter), and RPGs (Role Playing games) You name it, it can be used for it. It can be used for a variety of things.

When I was out of the country, I used this to talk to my boyfriend without incurring any phone fees. =]

It's free to download! (YAY!), and only one person has to pay for hosting and it's relatively cheap! (You can host it yourself for free, but the host has to stay online the whole time for it to work)

So buy a mic and you're good to go :D
