Hey Pordobolito,
As wendy says, you can earn points on as many rooms as you like, as long as you sign up through us and you don't already have an account there.
I took a short look at your account and I guess you're talking about 888poker at the minute?
Basically what happens is that the poker room will send us activity data about how much you've played and raked so that we can work out how many StrategyPoints to assign your account on a daily basis. This can take a couple of days though, one day for the room to send us the information, and another for us to upload the StrategyPoints so that they appear on your account.
For example, if you played on 888poker and raked $1 on the 1st August and $1 on the 2nd August, you would then receive 4 StrategyPoints on August 3rd and 4 on August 4th just for your play at 888poker. On top of that, you'd receive a further 10 points on each day because for every active player day (where you play for real money) you earn 10SPs by default.
On top of that, if you deposit at 888poker, you have access to the $100,000 Weekly Depositors' Challenge, a $1000 Weekly Depositors' Freeroll, and a $500 Daily Depositors' Freeroll. Need more information on those? Click here!
If you have any further questions, please do ask 
Best,
Marc
