Jmeeting has a good chat system with video, and you can use your cam. I use it and like it. Its fun. Lots to see, LOL

Silverdaddies has a good chatroom. Can only look at 1 cam at a time though, but, there's more than older men in there, bunch of young guys in there also. Its also free to join.

AOL.
I always enjoy a good cam session
