I put this snippet together for my dev mud so that we could wizlock the mud and allow testing with mortals without having to unwizlock it. It changes the way wizlock works, as well as the location of the greeting screen. Its a modified version of AFK's multi-port system.
Any Questions, email me at novotellus@hotmail.com

Notes
----------------------
1 - You will need to create a folder named motd
2 - Inside your motd folder you will need to create a file called greeting.dat
- greeting.dat should contain your login screen (the greeting helpfile)
- Included in this snippet is a folder called motd, it has stock dat files in it.
