It is listed in the server list as "project 1999" and since it is alphabetical, it is quite low on the list.
As far as files needed to play on the server you will need to download the "spells_us.txt" and "dbstr_us.txt" in the Files section of our website.
You will also need to get the correct Nektolus and Lavastorm files which doesn't require downloading anything just following some directions, which are also stickied in the Files section of our website.
Source updates have been happening quicker than I can keep up the past few days. There is a great team on board at Project 1999 who are dedicated to making this project the best that they can. So as Dibalamin said, Keep your eyes peeled.
