SupportPress Premium Theme by WooThemes

SupportPress is our second application style theme designed to create a clean and simple, yet powerful help desk using WordPress core functionality. Customers can submit support requests but are encouraged to check an intuitive knowledgebase to learn if their issues have already been resolved. Agents (your staff) administrate tickets by setting priorities and delegating tasks to fellow team members.
