ePassport deposit bonus questions

1. Once you have ePassport setup, is there a charge to deposit FROM a poker account INTO your ePassport ?

2. Can you setup an ePassport w/o loading it from bank account ? just create the user ID/password and then withdraw INTO it (like I did with NeTeller)

3. If there ARE fees to withdraw FROM poker INTO ePassport, then is it really worth setting it up for the $50 bonus on the party skins if you're losing $25 for your load deposit and then xx% on your deposits from poker to ePassport?

4. I've heard mixed things about whether it's a 10% up to $50 max or $100 max. some say you can deposit $500 and get $50 max, some say if you deposit $1000 you can get $100... should I bother trying for the $100 or just do the $500 and get my $50 and be done with it?
