o.O board/forum question....

[Revolution]

Now I have been using comps for a while (10+ years) but as for forums such as this its a relatively new thing for me. So my questions are:

1- The Signatures with pictures. As long as its on ANY web page can u use it like entering the bla bla www.adsfa.com/asdfjsdflkjas etc?
2- Attachements. My lil box on the bottom left says you man NOT post attachements. How exactly do I be eligible to attach them? Time? I believe I have seen equal ranks post them. Whats the catch?

Thank you for your support. No flames please Tech questions should have an unofficial rule about that.

Sincerely,
