I just had a look at the Symbian Wiki at www.symbianwiki.com and to me it looks like it has been hijacked: For every page there is either a obnoxious JavaScript box popping up that e.g. tries to automatically start a download of a "registry cleaner" or similar nonsense or a window with advertising for tripple-x sites.
One page viewing even brought up the Windows XP fax viewer which looked to me like an attempt to break in through the WMF file vulnerability.
As a page on the wiki states that it is hosted and supported by All About Symbian - maybe there is somebody reading this that could have a look what happened?
