Have you tried searching our online Knowledgebase to see if your question is already answered?
We can help with questions about how to use kahootz and the service in general.
We cannot help with questions about the content of your community, the project it may be running, or change access permissions. Those issues should be directed to the community managers whose contact details should be on the community homepage.
Please read our guidance on raising a support request to help you get the best support.
