Microsites 'Invitation Workflow' needs updating.

[nccchris]

Invitation Workflow for Microsites doesn't work as described.

When a new member who does not have an account on the control site clicks on the link in the invitation email, they see a page with the message

Sorry, you do not have access to this page
Perhaps you need to log in to the site.
You are not authorized to access this page.

I suspect this may have been down to this change

Whatever the reason, it should be explained that this workflow only works if the 'Who can register accounts' setting is set to something other than 'Administrators only'
