Hi Jane!
Try this
go to your gallery
click on the web address and copy it
then
Up at the top, click on where it says welcome, canine 46.
Go to edit signature
see the little symbol that kinda looks like Earth? Click on that.
a little window will pop up
paste your web address for your gallery there
once you enter (submit) that it will go back to where you can type
type in what you want your signature line to say (like My Gallery)
