How does the inbox work?  
 
I get stuff from people like Adam and all it shows it there page or profile or something, no actual mail to speak of, so there some way to open mail to read a message or something?  
I know I asked Adam for some things and then I got stuff in the in box, but all it was is just his page or profile or something….is there any actual mail, with words and writing and stuff, what am I doing wrong.
