1.) Check the site often for any new reviews. That way you're more likely to be able to comment on them and even get bonus points if you're one of the first.
2.) Write excellent, detailed comments. People will probably rate your comments as helpful, which gives you bonus points.
3.) If there is a program you use that isn't currently reviewed, suggest it to them! Not only for the ability to comment on it, but also for the 75 points you get just for having suggested it.
4.) If you haven't used any of the sites, it's not to late to start. It's a great place to find out about new programs. Plus, then you can comment on it once you've tried it.
5.) When looking at the lists of programs reviewed, pay special attention to the ones with a "*" next to them. This means that there's only been one (or fewer) comment so far, so you can get bonus points for adding one.
6.) Take advantage of all the other ways to earn points: rating reviews, rating comments, grading programs, etc.
7.) Referrals! For whatever they make, you will earn matching points! In other words, if they write a comment and get 50 points, you'll also get 50 points.
