In keeping with rules from a *certain board* of which I am fond, I believe it is fair to say that your signature and the space under your avatar are *yours*, and you *may* post links to your sites under in those two spaces.
However, websites which are deemed somewhat unsuitable, for whatever reason, we reserve the right to ask you to remove said links. I'm not too bothered about you advertising other boards, as we are all participants in the same hobby.
However, this may seem an extreme example, but links to sites with content not suitable for a younger audience, such as adult sites, will not be tolerated.
Here is a brief list I propose.
Extreme anti GW sites. Extreme (And I really mean, extreme, as I am not bothered much by these) political, racial, or religious sites. Adult sites. Sites which promote illegal copying of media.
Basically, use your common sense.
Apart from that, have fun.
Any questions, don't hesitate to PM, I am on a lot more than you'd think, and we also have the very capable Commissar Siegler and Colonel Talosof who can perform most administrative functions. If in doubt, don't hesitate to ask.
