"Friend" and "Profile Visitor Messages" I have some questions about the new "notifications". What does being a "friend" mean? Are there easier ways to communicate with "friends" than "private messaging" that anyone can use? I have started getting a number of "Profile Visitor Messages" that are really just the same as "private messages", asking me to solve a problem for them or asking about an earlier post. But, unlike "private messages" there does not appear to be any way to "reply" automatically to "profile visitor messages". Is there any way to do that?
