Hello, I have created custom-built private messaging system for a site and need a bit of help. For the user name select button I need either 1. Preferably a popup box with a list of names, where when you click Select, it closes and passes a var to the main screen, which puts the appropriate information in the text box. (I know how to do all of it except making the popup and having it pass a var to the main page and into the box. I would hope to refrain from refreshing (that would kill all the stuff they had put in the other boxes) but I guess it may be required if I want to keep it simple. 2. .. never mind. Thanks Edit: by the way I was also wondering what the best approach is to a "x amount of users online" would be. It seems fairly easy but the only obstacle would be taking them offline if they close their browser instead of logging out.
