The same way you change your shell password. My PPP password no longer works. Possibly login into your shell account to verify your password and modem communications. The POP and SMTP server is mail.cuug.ab.ca. You must give it your shell account user name and password and tell it to use those instead.
Chameleon seems to connect okay, but nothing works properly.
The Chameleon software does come in a fully functional version. Air News has a bug. A rare few people have gotten Chameleon working, and I'm not sure how they managed. Most people are unable to use Chameleon. Post the info described below to cuug.help and hopefully one of the other Chameleon users can help you out.
