re: Poker & Is there any way to transfer funds from site to site?
The only other way to transfer site to site is to use the 2+2 Transfer Thread. It is generally free (as long as you dont have to pay someone "vig" to get a trade done) but you do need to read the rules and do a bit of research which is spelled out for you in the introduction to the thread.
They transfer hundreds of thousands of dollars so it is used by many players.
Note: There used to be a TiltTraders site to do site to site transfers involving FTP but that site is closed down now
