Hello and welcome! When you click play now it opens up a telnet window. Telnet is a program used to connect to mud servers from most pcs. If the screen remains blank then you either don't have telnet installed (that would be weird unless you are on a MAC) or it is disabled. The easiest thing to do would be to dowload a mud-client. DL has a special client just for it which you cna find on the home page. Or you can google Zmud or mushclient. I am a little partial to mushlient because it is basically telnet which is what I learned to play on. If you log on through a client you want to type in
http://www.dl2.net for the domain name and then port 23 or 4000 either one. The login screen simply says that LOGIN: here just type the word "new" and it will walk you through the rest. If you have any questions or if this was terribly confusing just put them up here. You have stumbled upon a wonderful world filled with wonderful people and we are all willing to help. If you do get logged on don't be shy about aksing for help or using the newbie channel "in game type help newbie" And once again Welcome!
