Here are some detailed instructions on trialclix. This comes from a LUEser at LUElinks, and I trust his word since he's been informative on all the free stuff sites.
EDIT: I'm putting a list in this post of offers that DO NOT require credit cards. Keep in mind that they can change or be taken down at any time. I'll keep the list up to date as often as possible, also feel free to tell me any other offers that don't require CC's to complete in case I miss any.
By the way, any offers that have no points values most likely do not give any points at all.
All matchmaking services: 125-280 points
Movielink(NEEDS BROADBAND OR HIGHER!): 80 points
Shutterfly: 40 points (better than nothing though)

It's 100% legit, as people have received their $25 Amazon gift certificates from there, and I've been credited for everything I've done so far...

PROCEDURE:
1. Sign up. That's 50 points.
2. Click on Earn Points --> Education.
3. Request FREE information (no credit card!) from each college listed there. This took me 5 MINUTES. That's 815 points! (865 total)
4. This used to say do the Netscape offer, but they need a CC now. Damn.
5. Refer 1 more friend for a GAMECUBE or 5 more for a NINTENDO DS.
