There seem to be some restrictions if you do not create an account for wikiversity, like “If you are not logged in, there are limited selections available under “Tools” menu to the left. If you are logged in, an additional selection appears, “Upload file.” When you are logged in, you can upload a file to Wikiversity. If not logged in, you cannot upload.” + “If you are not logged in, you cannot “thank” or be “thanked.” + “If you are not logged in, the number of new pages you may create is limited. If you are logged in and your account is autoconfirmed, this restriction is lifted.” (source: https://en.wikiversity.org/wiki/Wikiversity:Why_create_an_account). Because of that I’d give 3/5 blocks.
