I am leaving this weekend to go to Portugal (IJCAR, to co-accept Herbrand award!) and then the following week I go to the RuleML conference at Stonybrook, Long Island.
The means that if you want to make coffee, now is your chance.  It also means that, if no one wants to make coffee, there will be a coffee vacation.

I will leave 600 cc of roasted coffee beans in my office.  This is enough for one day.  For other days, there is already-ground coffee (from Dana Street roasting) in the AI Center kitchen.
I usually use 600 cc coffee with ~ 1 liter of filtered water. Jason (cc-ed) can provide advice on technique.
You can volunteer to make coffee, make cookies, or bring in bought cookies.  Some reimbursement is available for ingredients or cookies.

I will resume making coffee on Thursday, July 14th (Bastille Day).
