Send the title/abstract to Michelle so she can put it on the Master Calendar.
Buy food: Pizza is good; order it in the morning and set it to be delivered around 11:45 (they can be late). You can get the P-Card from Mika (the day before, say), or get reimbursed after.
There are plates and napkins around the second and third floor (usually in some cabinets).
Transfer ownership of this site to a second-year.
Book a room: Pick a day of the week for the seminar and ask Michelle to get a room for that day for the entire term/year.
