questions about bankrolling from a first time bankrollee

[rheaume]

someone has offered to bankroll me. i dont think he's bankrolled a card player before. and i've never been bankrolled. we haven't worked any details out yet, so before we do, i have a few questions.

(i play NLHE and have been playing for about 2 years. i live off my profits. i want to up my limits, thus the bankrolling)

-what cut of the profits should the bankroller get
-what if i go bust? am i obligated to pay back the bankroll
-and some other question i cant remember right now, ill post it later

hope this is in the right place. try to be nice fellas
