I find the perfect module to do what i want to do in private messages (put a "Send author a message" to open a contact between a user and an author)
Unfortunately, i didn't find a way to put that "Send author a message" when i use views module. I display my article by fields and i don't find that field. I'm just begin to discover Drupal 7 so i don't know if i do the right thing.
I searched on the module section in drupal.org and i saw that the only module available for views with private messages was for Drupal 6.
Maybe someone know if there is a solution to integrate private messages with views (i'd love to have the same behavior that flags has with views: add the flag with add field) I looked at "advanced section" and "add relationship" to see if i can find something to add like flag but i didn't find anything.
ps: sorry if i made many mistake in english.
