I noticed that you made an account. I think you were trying to log on when I was messing with the server trying to get guest accounts to work (they do now btw). It was going up and down frequently then. Also, it doesn't seem to want to log in if you try to play in the browser by clicking the link. That could have been the problem.
The server isn't so much for playing and having fun atm. I have it up for testing as I want to look into gears that make the server work or not so much work and hopefully improve/fix some things. Currently in the process of updating the client to 22.4 and getting my multiboxing proxy up and running so I can easily stress the server myself. It'll probably take some time as there is a lot to be done.
