One of the easiest free methods is by voting for SWC on game ranking sites, here's how you do it:
- On the right-side menu, click on the number which shows how many CPs you have (in this case, it should be zero)
- Below the clock near the top-left of the page, click "Support The Combine"
- On the left column of the page, there's eighteen mini banners
- Click them all
- Repeat after 24 hours
You get 10CPs for every link you click, and I'm pretty sure you get more CPs if you actually vote for SWC instead of just clicking the links and closing out the tabs.
EDIT: If you'd like, I'll pay the CPs for you this time. Just assign me as commander of your ship and send me the URLs to the images.
