Could you give me a website where you can chat with mga kaibigan for free?

DeviantART has a chat, I think.

Real life personal friends?
You can just downloas instant messangers, like Windows Live, AOL, or Yahoo. It's possible that your computer came with at least one already downloaded. You can chat with pretty much any friend with an account of anything, or either program.
You can also download Tango or Skype.
I know there are websites where you can open a privat chat rooms where you can invite friends, but I don't know the names of any.

If you're looking to make new mga kaibigan online, you can go pretty much anywhere, just follow basic internet safety.
I used to go into Yahoo multi-player game rooms to talk to people. It was fun.
