Gmail
This is way off-topic for this blog, but if there's still anyone out there who wants to try Gmail I have four invitations left.
Not that I recommend it. For me, nothing beats the Outlook integration of e-mail, contacts, calender and more. When I need webmail I use the account that eventually will end up in Outlook. But it's always fun to try things. E-mail me: "fredrik (at) corporateblogging.info".
Update: Three Two invitations left. No more invitations.
