Hi, Dan,
If you check out the posts I've made here, you'll see I'm a plain-speaking guy who's not afraid to offend people. If I thought PokerStrategy was a scam, I'd tell you.
But this site is totally legit. I passed the quiz and got my starting capital (on William Hill) with no problems.
I also opened an account on Cake through the referral link here, made my own deposit, and have been accumulating rakeback and strategy points like clockwork.
In many ways making your own deposit to get rakeback is a better deal than getting the free starting capital. My rakeback is outpacing my losses on Cake. But check out the Cake forum for my post on withdrawal and P2P transfer restrictions there.
If you look in the William Hill forum, you'll find several posts from people who have had similar issues with their software, especially on laptops. William Hill has a bad interface anyway, but it's not a bad site to play microstakes BSS on.
Friend me if you want further input.
