The only way I know of is to subscribe to a thread so you get email notifications on when someone replies. >: And if you mean "view conversation", that's just to see all the visitor messages you exchanged with someone else~ private messaging is through the private messages inbox, which are private. ^^
Role Playing is like writing a story but with multiple people. You each assume a different character, or "role" in the story. Pretty simple. It is also kind of like a game in that sense too. Since it involves the ideas of multiple people constantly going back and forth... it tends to interest more people than writing fan fics.
