How do I get my signature to link

Hello,

I'm new to the Nature Photographers Network so please forgive me if this is a dumb question with an easy-to-figure-out answer. :)

I was wondering how I can make my text linkable in my signature.

I tried using HTML <a href="">link</A> (etc.) and I've also tried putting an <HTML>before and after</HTML> my signature.

Is there another web language I should be using?

Thanks in advance!

refer to the "Text Style Menu" below the dialog box to enter comments, all the instructions are there

Thanks so much! I didn't see that. :)
