outlook calendar replacement
in my quest to have a more uniform experience between my windows and linux worlds, ive switched over a bunch of programs to open source. here's a couple of em:
AIM -> gaim
IE -> firefox
outlook -> thunderbird, almost!
i want to switch to thunderbird for everything but i need a calendar replacement for the outlook calendar that is open. preferably something based on iCal, or whatever the mozilla standard is. i tried mozilla calendar plugin and mozilla sunbird, but there's a reason both are buried in the mozilla site for now (plenty buggy).
does anyone know of a solid calendar app that can be installed in both a windows and linux environment?
