Hi,
Every now and then I check for the 'Recent Changes' on the wiki. The following page caught my attention:
http://wiki.winehq.org/MaartenLankhorst/SOC2007
This page is actually named "MaartenLankhorst/SOC2007" and is a child of the 'MaartenLankhorst' page. This page messes up the logo in the top-left corner.
When looking at the properties of the logo it shows 'http://wiki.winehq.org/MaartenLankhorst/logo.png' instead of the correct 'http://wiki.winehq.org/logo.png'.
The same logic is true for http://wiki.winehq.org/MacOSX/FAQs (and probably others).
Just thought I mention it.
Cheers,
Paul.
