Summer and Michael,
Even without a Leader to lead, one of them, or me, can help you with a template. You don't have to be a top-level project to have one. That should help with notating that a profile is in the project. It still is better to categorize under the narrowest category, but templates don't have to categorize, so they can be placed on all appropriate profiles. Email me if you want a hand in getting a project template set up.
Otherwise, to give input on categories that are important to any project, that project should have at least one liaison to the the Categorization project, if not more, so that you can weigh in on important related decisions and bring up important discussions, like this one! :-)
