How to add 'Send author a message' Tab on user profile

I apologize if this has been addressed. I searched and searched but can't quite pin this exact issue down.

I am using Advanced Profile Kit and each user's profile is at user/%

Upon editing their profile content and saving it, "Send author a Message" is linked on their profile.

But, How can I make this a tab on each user's profile instead?

example:
VIEW | OFFICE LOCATIONS | SEND AUTHOR MESSAGE

As of now, I have a few other tabs I've created using Panels. I have a panel page at /user/%uid/office-locations using a context "node add form" and its Menu Tab: 'Office Locations' so profile authors can click "Office Locations" tab and add their office locations.

I thought I could do something with the settings in Panels in order to get a "Send Author Message" tab on the user profile page in the same manner. Am I wrong?

or can i at least have a tab "Send Author Message" linked to a path such as: /messages/new/16 '16' being the uid of the profile being viewed? Maybe I can accomplish this using Views..

Or could someone reference another thread that I looked past?

Thank you!
