Migrating from KMail to Evolution

I've decided to give Gnome one more go (I've been a KDE user so far) so I installed Ubuntu 9.04 on my laptop. What's more is that I decided to use only GTK applications, nothing Qt whatsoever. At least for a while, to see how it goes : )

So far, nothing but confusion. What was notable though was the painful migration of my e-mails from KMail to Evolution.
