Hi Katherine, let me see if i can walk you thru this
1) go to your profile
2) click on edit signature (on the left column)
i'm going to use "MY gallery" as a sample to the link
3) Type MY GALLERY in the signature box
4) highlight MY GALLERY with the left button of your mouse
5) then click on the icon "insert link" <--looks like a globe with a paper clip icon
6) you should see another box that pops up that said enter your url of your link:
7) enter your gallery URL in that box --- it should look like (this URL address is for my gallery...) : "//www.splitcoaststampers.com/gallery/showgallery.php?cat=500&ppuser=63727 "
click OK
9) you should see a bunch of stuff in the edit signature box --- just click save signature and you are done
i hope this help ...
