Hello,
I am new to this software, and i want to know more about this.
I have a few question in my mind.

1) I have not own a server but i do rent some space on other server for hosting my website, can i just put the script of World Wide Messenger inside the server and run it, if i buy it?

2) My server is running on Apache server, support Php, Perl and Mysql, can my server support this software?

3) I have downlaod the test script for World Wide Messenger, and put the script in my server to test, but i can't found that page, while i access that page, what should i do?

Thank.

If you can execute the test script, then you should be able to install the Messenger on your server.

I am not sure why you would not be able to find the script after you uploaded, you may want to read your servers manual.
