A wiki is a type of website that allows collaborative editing of its content and structure. The WebCT Support Wiki at Ulster University is built using Confluence wiki software and houses solutions to common WebCT problems for students and staff. It sees 400-500 page views per day, peaking at 1200 during busy periods like the start of semesters. The wiki was updated in 2010 based on usability testing to improve its design and user experience.
