Not working in mainspace - why?[edit source]

This doesn't seem to work in mainspace - I tried using namespace names of Main, Mainspace, Article and 0. E.g.

{{List subpages|AT CAD Team|Main}}
Pages with the prefix 'AT CAD Team' in the 'Main' and 'Main talk' namespaces:
Main talk:

Subpages appear to be turned on (note link to root page at AT CAD Team/AT Interstate Traveller). What's going wrong? --Chriswaterguy 00:05, 7 June 2011 (PDT)

One step closer - this now works for mainspace in mainspace. It still needs revisions to work for mainspace pages outside of mainspace. --RichardF 13:32, 26 January 2012 (PST)
I made a number of updates that should better display mainspace pages in any namespace. I dare you to say that ten times real fast!!! :-) --RichardF 12:41, 15 March 2013 (PDT)
