1. In the Nav bar at the top of the page click on 'Search' then click on 'Advanced Search'. Look for the field that says "Search by Tag" and type in 'free wso'. Then where it says "Search in Forum(s)" select only the "Warrior Special Offers Forum"
Run this search and you will pull up all of the free WSO's. People often offer some great knowledge in these for free. Pick up a few that appear to contain knowledge on what you are specifically pursuing.
2. Don't spend so much time reading the free wso's or the forums in general that your productivity starts to suffer. Get back to work!
3. Don't just be a total freeloader. If a Free WSO taught you something new and helped you make money then consider buying a product from the author of the WSO in the future. Odds are that their paid products have more to teach you.
I hope someone finds this useful. I know I've mined some good info out of free wso's.
