"The gnome calendar is integrated with evolution. Good thing. Now, when I install
ubuntu and try to add a event to the calendar, a wizard is launched asking me to
tell my email account (!!)

I don't have an email account, I use gmail. And anyway - I'm trying to add a
calendar event, nothing related at all with email. But it's worse, apparently I
can't launch evolution without configuring an email account. It asks me to
configure my outgoing email, and I can't get rid of that screen by setting my
outgoing email to "sendmail" (which is somewhat weird since ubuntu doesn't
install senamdil, maybe it wants to mean "local email server") It also asks me
to set my local time configuration, despite of having already set that to
"Europe/Madrid" in the install...


IOW: I don't think that it should annoy the user at all when adding a calendar
event."
