They have been offering reloads approximately every month. It looks like to me they are moving in a different marketing direction now though. It does appear that some bonuses are account specific, so I'm thinking you have to use the ones they offer you now.

Yes, you can deposit, clear the bonus, then withdraw everything right away. Depending on the method of deposit/cashout you use, it might take a few days. IGMpay took a week for me one time. I'd recommend using Neteller.
