Have you got cool activities that you want to invite people to? Do you have international conferences you’re attending that you want your distant friends to note so that they may set an appointment with you alongside them? Are you a fan of colors red and yellow?
Then, sign up with upcoming.org, a Yahoo company that provides calendaring services like Google Calendar. It’s much cooler than the latter. Although, as a Google Calendar user, you may still opt to sign up with upcoming.org and have two services inter-operate.
There is also a tags and groups feature with upcoming.org. I, for one, have just signed up with the group called ICT4D (information and communications technologies for development). All events across the globe that pertain to ICT are posted by the group. So if you’re an ICT activist, better sign up with upcoming.org and the ICT4D group.
