  * Allow Subscribers (technically anyone who can access the CE form) to Add New Venue for The Events Calendar Community Events add-on
  * 
  * Here's a view of what Contributor users have permission to do: http://cl.ly/1M0c1u2x462a
  * If you want Subscribers to be able to Add New Venue, you could enable them to have `edit_tribe_venues` permission, which could be accomplished by using a plugin like https://wordpress.org/plugins/user-role-editor/ (third party, not guaranteed) or via this custom code snippet (resolves CE capabilities issue)
