I finally after too much of pondering started my project on googlecode. One of the best features I liked about googlecode was the revision control for wiki, where I can add/edit the wiki pages locally offline and then commit/push later.
I have pulled the wiki to my local repository, is there any good googlecode-wiki-toolbar-attached editor for googlecode wiki, as from my knowledge evey wiki has its own syntax for writing.
Or if someone is also using a local repository for wiki.code.google, what practice are they following for writing the document for online collaborations.
