[horde] {End User} Deleting old events

[Jerry VB]

Hello,

I'm just and end user of Horde. My email provider is using Horde H3  
(2.1.1). For the last couple of months I've been populating the  
Calendar with lots of work related events. It just occurred to me, how  
do I delete the old events after a year goes by? How do you do this? I  
cannot find an easy way, other than going back and selecting each and  
every old event and deleting them one at a time.

Thank you,
Jerry
