If I can I'll be there mining azurite for traders on my core| miner. However, I would like to suggest changing the dates for this event: Setting events to occur during the weekday is a bad idea. Most of us work, regardless of timezone, and are unable to participate in weekday events. Move it to the weekend and you'll have more people willing to participate.
Typically its also better to give at least a week's notice for things like this. I believe there are other events running this weekend that will be taking our time up.
EDIT:
Also, I thought it was more the GMG that were at war with rheinland, rather than actual kusari?
