I'm trying to talk to my brother with my microphone of course, via Yahoo Messenger. I'm using GAIM and i didn't see any option of this sort. What do i have to do?

There is bad support for voice conversations in Gaim (I got it to work but it is a bit tricky, many other program like aMSN also has support but very limited and not very easy to setup). I think gnomemeeting (or something) should work, although I have never used it and cannot help you further on that one. But it is something simular to Netmeeting.

If you need something that works and quickly I would recommend Skype, it's not opensource but free and works on Windows and Linux.
You could use gnomemeeting as Ephracis said but you need to meet it's dependencies and Slackware is no more current with Gnome.
There are other alternatives like Teamspeak where you could create a server and tell your brother to join it, it was designed for games, but works well for the family
As Gaim, there's a project planning to add support for video and voice called gaim-vv (when it's ready it will be merged with gaim) but there's no stable code yet.

Teamspeak. Easy. Done

Happy hunting!!!

I agree with gbonvehi. Skype is excellent for voice-chatting and supports dialing to real phones (for a little cash). Computer to computer dialing is free.

For voice and WebCam support for yahoo messenger you can try gyach :
1. Download http://www.politicalcrossfire.com/te...nstall.tar.bz2 , and save it to your home directory (important!).

2. Run these commands in the terminal, in sequential order:
Code:

tar -xjf gyach-install.tar.bz2
cd gyach
sudo ./install

gaim-vv is another choice
