AOL Instant Messenger Protocol

The AIM protocol will open an AOL Instant Messenger IM window with the attributes specified in the link. links begin with aim:goim?.

Examples of modifiers:

screenname= 

aim:goim?screenname=notarealuseratall

mesage= 

aim:goim?message=nothing+at+all+here

Ironically, Wikipedia only supports common protocols, so those adresses must be copied and pasted into a browser to work.
