Email notifier for multiple GMail accounts

In Synaptic Manager, install the package checkgmail
Installing it in Ubuntu 9.10 fetches its latest version 1.13+svn43-0ubuntu1.

These steps demonstrate setting up 2 gmail accounts for checkgmail to notify you with:
1. Set up your first, and default profile
Applications > Internet > CheckGMail

2. After that works, quit checkgmail to setup your 2nd profile.

3. Open a terminal window, and type the following, replacing the my2nd word with your preferred profile name:

checkgmail -profile=my2nd

4. After that works, quit checkgmail again.

5. To make the two checkgmail profiles to automatically start at boot-up,
System > Preferences > Startup Applications
Click Add to add your default profile.
