My calendar is getting heavy. It contains iCal information since the beginning of times (mid 2004). This did not bother me so far, but does now. Indeed, I am synchronising my work calendar (which rules my time from a windowx XP machine and a synchronized work-issued blackberry) to the mac via the Plaxo sync tools (to the PC and to the mac). Now, Plaxo tells me I have too many calendar items on my calendar and refuses to sync anymore, until I reduce the number of live calendar items. Time to do some archival copies.

How can I save my years of calendar items?
How can I edit them (print)?
How can I look at them online?
