My schedule at Worldcon - an addendum

Turns out my schedule at Worldcon this weekend will be a little busier than I'd thought. Since we last weighed in on where I'd be and what I'd be doing there at what time, I've added a couple of panels to the roster: a 10 a.m. Sunday panel talking about the perils and pleasures of collaboration in P513B; and an 11 a.m. Friday kaffeklatsch with members of the Cecil Street Irregulars workshop in 521C.
