1) Here is a download link for a 'Crypto'
Counter .
2) Freerolls I believe. I have never used them on InterPoker but did use some on CarSun(another Crypto) once for a freeroll.
3) Forget about their email. Call them if you really want to know something though you may be put on hold for some time.
As to the pound games, they rake the same but in pounds so the rake is 1.82 times greater in those games, beware.....
