With the Course Creator tool, users input basic information about their course and then click 'create my course'. The system uses the 'title', 'term', and 'school' to form the url slug for the course. If a user includes leading or trailing whitespace in one of these fields, then the resulting url slug will have multiple underscores in a row, which is a little confusing. Such cases also cause compatibility problems with templates that link from Wikipedia to the course page, since Wikipedia templates may strip out the extra whitespace in the url.
