We've pushed some updates to UploadWizard, most notably:
* disabled multiple-file selection in browsers where it didn't work * files now start uploading immediately when selected (this can be disabled server-side if there are problems with it) * improved category input fields * 'skip tutorial' step is now saved as a pref instead of a cookie -- so the tutorial won't come back every time you switch computers anymore! * fixes for when pre-upload thumbnails do and don't get drawn * initial API for fetching upload campaign metadata ('action=uploadcampaign'), to be used by Wiki Loves Monuments mobile app
Don't be shy about giving feedback!
