Technically, if he followed Stickly's instructions and used XGUI, that means he's using SVN.
Which, should be located under the SVN Stuff forum.
BUT, I didn't move it because, well, even the (old) release version of ULX has a MOTD file that can be manually edited, and enabled or disabled (though, I don't think it includes the ability to display a URL (but, been a while, I forget)).
So, just left the question here.
