At the moment, publishing projects is a manual process. You'll need to find someone with access to the server who can post your project's files (found here).
The project files are separated into category based on the creator, and are posted on the server here.
The way to play a project, at the moment, takes some manual url manipulation. Namely, go to this project page, and change the url by replacing 'USERNAME' with the user name, and 'PROJECTNAME' with the project name.
The analytics for a given project currently appears in this folder on the server. The json files for the analytics are separated into folders for each user, then subfolders for each project.
