Rules On Signatures?

I know this is kinda of a newbie question but are there specific rules for signatures?

Like maximum lines of text or images or links you can put?

Can anybody put a link or image in their sig or do you have to wait days or get a certain of number posts?

Again, I know it's a newbie question, but the forum rules does not say any specifics and I wanted to ask just to make sure, so I do not break any rules like what happened at another forum I was in.

Nah, you should be good on posting links in your signature. Just maintain a certain aura of decorum in your signature. Avoid profanity or obscene/ racist comments. Don't post anything illegal.

There is a certain amount of characters that are allowed in a signature, but as long as it's no bigger than mine, you should be okay. (I'm at the max limit)

You should go to like BF3 stats if you have that game and get a girl in a thong signature

Yes there is. 1,000 character limit.

You have to go with the BF3>MW3 for sure though.
