Note that after August, 2014 this does not work for un-official CPCUG email accounts.
Access to CPCUG Webmail uses the main menu item "Webmail," at the right side. Click it.
The login screen is for Squirrel Mail, just as it was in previous years.
The "Name" is the username or leftside text your email. The "@cpcug.org" portion is left out. Your password is case sensitive.
This should work with mobile devices, but not all hardware has been tested.
