The server is called "NeoGAF Unofficial ARK Server". You'll have to find it using the Steam server browser and then to easily find it again add it to your favorites. I'm going to hide the password in this post for now and see how it does.
if you quote this post you will be able to see the password. Please be patient with this server as I have never owned a server before and done any of the heavy lifting!
edit - and good timing, just like that I have to update it. It should be up in 20 minutes or so!
edit2- and it's up again, enjoy!
