Those websites are not exclusively chess sites, and offer other games.
I tried ItsYourTurn - but I can't get a rating there.

There is pretty good participation and reasonable free play (I think up
to 15 games, one move per day) at itsyourturn.com. They have horrible
site management, though, and a paid membership just rewards them.

goldtoken.com is much smaller, allows 15 free games, and has a
smattering of better players, but a nice community.
