I've just managed to work it out!! Carcrazee, you need to type your link in the signature like this (go to update profile):
Type the following in square brackets:
url=http://public.fotki.com/62704/
Then you can write some text of your own choice (like mine which is My Photobucket)
and then the following in square brackets again:
/url
I have not shown the square brackets, as it then becomes an active link, so one cannot see what to type.
Heres your link done properly:
George's Fotki site
If you need any more help, let me know!!
Marc
