Online Chess

I used to be a member of ICC and I love the site because there are several titled players I could play with and so many players that you won't run out of opponents. So I wonder what you don't like about that site, can you share with me? Anyway, ICC is a paid site and because I teach chess online I would rather be active in a free site so that my chess students would not have to pay for the chess site to have lessons with me online. Now I'm using chess.com for my lessons and I recommend it as another good site. Chesscube I'm not so familiar, but I will check on that soon. I have heard about yahoo chess and a lot of players using that site, but when I tried to go there it is hard to find opponents when you are beginning because not so many players wanted to play with someone without definite ratings yet, but maybe after having a legitimate rating, I would then have more opponents accepting my seek there. Babaschess is another site I tried but they have less players than all the other sites I have mentioned. In my experience, I liked ICC and chess.com the most. I almost forgot, USChessLive is worth mentioning.
