Allotalk is the best chat room site i have ever seen. It has 3 separate chat sites called teens, strangers and singles.
I personally like teens cos i am a teenager i made so many cool friends there and i can say this teen chat site is the safest chat site for teens. I also have been on stranger chat talking to strangers and also it has moderators 24 hours a day moderating the chat rooms. Its a safe place to chat and have fun with the friends from all over the world.
