We just updated the code which generates an Upcoming events block at the bottom of the frontpage.

You can choose to:

• ... click on Upcoming events, which gives you all the events of the current year
• ... click on a specific event, which gives you details about the event

If you want to look at older events, you could browse to News and articles > Agenda. This will give you a list of all events, seperated by the year the event was organized.
