I'd like to be able to submit a rating for pages using the API.
My Wikidot editor (at www.wdeditor.com) has a feedback system similar to this one where users can post bug reports and wishes. Each page has a Rate module on it.
I am experimenting with the possibility of letting users submit requests and bug reports using the API, directly from within the application.
Being able to rate their own wish up for them would be a huge bonus, saving the user from having to visit the web page and do it themselves.
