Features / Usability

Hi Angie:

If the users have the appropriate permssions, they should see the button to add new events

Please, provide specific urls for each step.

the module calendar, in theory, allows to display a button to any user in a group which has the permission to add events.
See Permissions (on a Global level, and object level; you can skip permissions on content categories for a while, while you are mastering the basics) and Module Calendar New
