maybe this can be of some help.
one way of displaying your link is to just have the whole link in the message - like this, using my quite pitiful gallery.
puppypaws's Gallery at Splitcoaststampers
this is what is problematic for the original poster.
but here is something you can do. you can use a word to substitue for the whole link.
gallery
what i did was use the left bracket, then i typed url= and after the = i copied in the whole address for my gallery, starting with the http:\\ part
at the end of it all i put in a closed bracket then i typed the word gallery and right after that i did the left bracket and then a /url and then the right bracket. here is what it looks like but with the ( instead of the bracket.
(url=http://gallery.splitcoaststampers.com/gallery/showgallery.php?cat=500&ppuser=6854)gallery(/url)
does that make any sense?
sorry - several edits later i think this may make some sense.
