Here's my problem. I need a calendar app that rudely beeps to tell me when to go to meetings and such. In Ubuntu, that means the Evolution mail client, which has an extensive calendar function, or so I'm told. But I don't run Evolution. I use Thunderbird to manage my mail, and Thunderbird doesn't have a calendar function ... or does it? [My apologies for the "Bohemian Rhapsody" pun in the headline - Steve]
