Could 당신 give me a website where 당신 can chat with 프렌즈 for free?

DeviantART has a chat, I think.

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

If you're looking to make new 프렌즈 online, 당신 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.
