As long as you leave your mudcat cookie on the machine, you should be recognized when you connect with the site. If the cookie gets erased, then you'll need to log in the next time you come back - and get a new cookie.

The problem, apparently, was that logging in wasn't working?

The clones are the best ones to help when that happens. There is help on the log-in pages, and also at the Help button. Frequently though, it's just a matter of not remembering exactly what info you used when you created your MudID.
