I am going to ask Sile to pmail each of you his address. I mean you have it anyway from the mail list. Each of you send a nice polite postcard describing why it's important to live up to the group's responsibilities. Then politely inquire as to his health (a Tony Soprano subtlety). Do a bit of begging, then quietly imply the next package will contain chicken (or use your imagination) entrails and you will be putting a benign hex upon his head.
All and all, keep it light. Next we send in the RCMP.
