Comma separated list of forms that can be attached to topics in this web. See DataForms for more information.
Access control
Users or groups who are allowed to view, change and rename topics in the Main web.
Remember that an empty setting is a valid setting; setting DENYWEBVIEW to nothing means that anyone can view the web.
If you intend to lock down the Main to only allow registration, you need to add the built in RegistrationAgent to the ALLOWWEBCHANGE setting.
