297389 Chat Modifications

I have a chat script that i would like to incorporate a "users" box and also show the total amout of users online. the user will type his/her name into the username box once listen or post button is pressed the username will stay in the username box (as it already does) plus it will be added to the "users" box. if the user does not post for 20 minutes they will be added to the lurker tally and taken from the "users" box. Currently there is code to prevent the user from choosing a registered moderators name i would like this code to stay in place, plus it does not matter if there is multiple users with the same name. i would like the user to be able to choose a name from the select box and have that go to the chat script eg: Cam says to Jen --------message------ cam being the user typing the message and jen being the person he chose from the select box At the bottom of the control box i would like to display the total amout of users currently browsing the board (chat script) this will be displayed as $amount Of Lurkers Online. The script is perl with an editable template. I have set up the script (not 100% ) to show what i mean and to be used for testing the modifications. When it is up and running i will integrate the script into the "live" script The script can be found at [login to view URL] although this has no adult images in the test script it is an adult site so if this offends please dont apply for the job (sorry)
