best way to clear bonus at pokerstars?

[Quagmire 0]

I recently deposited $500 at Stars in order to take advantage of their once-in-a-millennium deposit bonus. I have to accumulate 500 Frequent Player Points to release the bonus, and am having a hard time making a dent in that number.My normal games are 1/2 Limit and either $25 or $50 NL ring games. I feel like I've been busting my butt and I've only earned 150 FPP's so far. I like the $50 NL game at Stars a lot, but the points just don't add up quickly in that game. I know multi-tabling can be huge help, but my attention span and my computer make playing at more than 2 tables virtually impossible.Does anyone have any suggestions for games within that bankroll that will generate points more quickly?
