The VIP system isn't clear at first, I'm still getting getting used to it. I believe you get 100 points for every €1 you rake. There are mile stones you reach where you get rewards, stuff like 4x Sng tickets, 4x tournament tickets or cash straight in to your BR. The rewards get better as you go up.
To help you get more points, they also have minor and major challenges. The minor ones are things you get without trying, like raising pre flop 10 times. You usually get an extra 100 points for a minor challenge.
The major challenges are things like check raising in the BB when someone raises pre flop, this can get you 1000+ points. Once you complete a challenge it gives you a new one.
I find myself completing the challenges without trying. They just happen. I'm sure they reset each week also.
You can make 5 usernames. i only have 3 but i change them regularly. I could go a week with the same one and other times I could change it 3 times in one day. Depending on how reg infested it is.
The software is simple enough to navigate around. If you go to "view profile" it will tell you all about your points and next challenge, and what rewards you can win.
Maybe also worth mentioning that is MAC friendly
