(Originally by AOL-Files staff member Tau)

This file was originally contributed to me by Maxis. He claimed that his aunt worked for AOL or something. Tri e-mailed me regarding me previous thoughts on this and informed me that this is not an official chat room code, mainly because of the

SendChatRoom( hAOLWnd, "[-=+] ------------------------ [+=-]" );
Wait( SCROLL_WAIT );
SendChatRoom( hAOLWnd, "[     ] Highland Loaded [     ]" );
Wait( SCROLL_WAIT );
SendChatRoom( hAOLWnd, "[-=+] ------------------------ [+=-]" );
Wait( SCROLL_WAIT );

As he stated, it looks as this is the beginning of an AOL prog.
