What server address am I supposed to use? Every method of logging in so far has bought up errors, and I don't know what to do.
With most servers, you don't need to enter the server address. Just enter your contact ID and optionally enter your password.
What I think he means is that when you add a new account there is nothing in the server name drop down. I have been looking around this site and see no instructions on what server to put in there.
IE Something is missing in the instructions.
I had the same problem with a programmer-art.org server account. I had to uncheck the "Use secure connection" option under the "Connection tab before it would connect.
