I apologize. I only now saw your complaint here:
Where on earth is the private messaging feature here on WPQuestions.com?
I am embarrassed to say that we have not yet built this feature into the software. Up till recently, it seemed enough to be able to send people email. However, I agree that we need a system of private messages on this site.
We are working on a massive rebuild of the user
profile and dashboard pages, sort of like we just recently redid the front page of the site. Many new features will be rolled out over the next few weeks, including a system of private messages.
I thank you for reminding me how important this is.
