So, I went and setup my forum software, bought a nice skin and create all the forums, a few users were created among friends, no more then 10. They're not interested in the forum topic, just help me to setup the registration.
So, there are no other users but me. I create a few posts a day quoting news and interesting topics, but just that.

I got some links in directories and I'm running a small campaign and receiving about 100 users a day. NO ONE signup. Of course, I don't blame them. Forums are almost empty. I'm running some automated RSS feeds so, there are some posts in a few forums, but still, people don't even signup.

I have tested the signup process just to be sure it is working fine and it is!
