Not sure if to post this here or in the Poker rooms forum. Decided on here as there's a marginally less chance of being mocked

As I've mentioned I have a little over a hundred dollars in my account at Party Poker. They're currently offering a 15% bonus deposit over the next week or so.

Is it worth cashing out my $100 and then re-depositing it?
Does this work? (Seems that it would be silly for them to allow this).
Is it worthwhile? (I'm not sure how much I will pay in fees if I deposit it to my Netteller account and then put it back).
