When looking at the exported ICS file from my calendar (either using export or via caldav sync), I see that all events have a priority set to 8 - why is that?  How can I modify it?  Can I set a default for all of my events?

I use a Orage on my desktop to display the events, by default it doesn't display events with a priority value of 8 higher, and was not showing my events from Zoho.  Easy enough to fix, but wondered why the decision was made to default to 8, and whether that is something I can control as a user.

Thanks
