America Online’s Instant Messenger (version 4.7 build 2480 and better) can accept URL-encoded input and display it within a new instant messenger window. This works very much the same way that you can pass variables for the to, cc, subject and body of an email message. The only potential drawbacks are that it will not work with any other messenger product, nor does it appear to work within the AOL application to open an Instant Message window and instant messenger must be running when the user clicks the link. Utilizing a couple of server variables (host, script_name and querystring) you can link every page on your site to be sent via AOL Instant Messenger.
