Don't know if any of you play these like I do but a great one just started up.  I would be super appreciative if any of you tried it with my ref link.   http://www.avabur.com/?ref=1226  Of course I would be happy to answer any questions you have.  Thanks and if you just want to check out the game with no ref no problem there either.  Just want to see it grow :).

you should try Sryth its text based as well

I registered, but I don't understand what's really happening.

I've tried a bunch of these and the best I've found (and which I play every day) is Drakor. Very friendly community, lots of documentation (which you can read before you join!), and tons of stuff to do.
