Hello. I've made a Counter-strike Source clan and we are needing a FREE server. If you can make us a server, please contact us at ivo.a.nunes[at]gmail.com and I will tell you the details. If you do it, I'll make a sponsors page on the website to put you there and will put your logo/name on the first page.
Note: the website is in portuguese. Try to see it with google translator.
