You type some text. You highlight the portion of the text that you would like to make into a link. You click the link button. You type the URL for the link.

You're done.

Gordy,
Sorry to disturb you but i cannot get the link to my club http://amss.be into my signature.
When i put it into the url box it is invalid. When i put it into the signature box i have to many line's.
Still i do not have a gif possibility. And there is no box for smileys into the text, and i cannot color the letters or make them bigger, fat text etc.
Hope you can help.

Marc
