Earning FREE credits

I am a member of several sites where I can earn FREE credits for my advertising. I have as a "working tool" a Microsoft Excel document where I have listed all my sites (with links to the login page) to handle all of my TE:s easier.

One of these places is LinkGrand, what I want to call "stay at one place"-traffic exchange (TE). It doesn't open a new window for every new paid link that you click on, and it bring you back to the linkpage where you started to continue to click your paid links. VERY GOOD site, in my opinion.


(So I worked my links for the day and moved on...)
