While we're touching on the subject of the wiki, it'd be helpful to have a more functional editor for it - along the lines of TinyMCE or fckeditor.
To be honest, editing the wiki at the moment is a bit of a pain, and I'm not inclined to do it unless I'm feeling really inspired.
Also, I'd like to see the MC13 forum broken up into the more traditional Support, Feature Request, Discussion etc boards. This makes it easier for people to search for already solved problems as well as generally limiting the number of repeated discussions.
