How do I put a link on my signature?

[Rhaegar I]

I want to put a link to my new ATL on it, but I have no idea how to do it.

Please, don't respond all at once.

Can someone at least show me a guide to different stuff like this?

Copy the url, click Insert Link, when you see it, delete the highlighted part and put what you want.
