Hi charliebeth,
Yes, you will continue to earn Strategy points on all of your tracked accounts that you set up via the PokerStrategy.com links and bonus codes.
You can of course continue to play on your existing account (and enjoy all their tournaments, future promotions etc) or transfer to another PokerStrategy.com partner site or indeed play on several at once.
A lot of us have tracked accounts on several different PokerStrategy.com partner rooms. It's always good to change from time to time and you benefit from all of the promotions that both PokerStrategy.com and the poker room themselves run.
At the moment the only way to earn points is by playing poker on your tracked account(s), you can't currently earn them by reading the articles. More points in a month will increase your status however which will open up additional material, videos etc.
Hope this helps, shout if we can provide further clarification on any aspect.
Best regards,
Bart
