Make More Project Profile Actions Visible to Guests
Unauthenticated / guest users are not aware of the Review This, Join Group or Contact Us options. These are important actions that are currently hidden from guests.
It would encourage site visitors to join, if these actions were listed in the profile portal layout by default for guest users.
Clicking on one of these actions could produce the 'You must be signed in to...' message, similar to the web site tab portals' ActionsPortlet.
The Contact Us action could add a captcha for unregistered users, rather than requiring an account, although it would then require a from email address entry.
