Lavaplace is a niche dating site where you can meet women from Russia, Ukraine and ex-USSR states. They offer both Russian and English chat rooms where any member can enter for free and chat with the other members present. I've tried it myself and I can tell you that the members do use them so luckily if you go there you'll find someone to chat and who knows you might find more.
Friendfinder is probably one of the most publicized non-adult site to meet people online. A little known fact about Friendfinder is that they offer a variety of chat rooms where any member, even those with a free membership can chat for free. All you have to do is create your free profile and click on the link in the top menu. I've also tried the Friendfinder chat rooms and I can tell you that the members are very nice.
