How do I get credits?

I am wondering if you can get credits any other way than just type posts and threads? Thanks in advance.

Yes putting tags , People need credits to unlock them . i think 8 credits to unlock one .

I'm asking myself the same question. I'm a bit scared about the amount of guarded content, closed communities and CAPTCHA/spam protection measures exist on the Internet nowadays. I alwasy thought of it as a more open-minded world.
