Looking good Wayne...
There may be a better way to do this than using the Infobox here, i'm worried that people may use a different name in the infobox than the one they created an account with and this could lead to some confusion. See this page for another option: Preload, then perhaps using something like {{fullurl:{{PAGENAME}} although thats not going to be the right one... it might put you on the track. Although, looking at the urls that are created using liquid threads i think this may be a bit tricker than it would have been before them.
