Because of the beverage policy, the party had to be closed. I don't know what qualifies as an event, but I bet that pesky Cambridge law would keep us off that list. I didn't know there was a gripe session or I would surely have gone. :)

Invites were distributed all day friday and saturday, perhaps your friend was in costume when they received the invite, or perhaps their regular attire looked costumelike to our friends, or, I hate to say it, perhaps one of our menfolk took a shine to your friend and just wanted to see them again. The folks paying for the party do get handed their own ration of invites and we can't really control who gets one. The best costumed person at Con could get missed if we just don't run into them.

Anyway sorry about that, we probably weren't even supposed to poster at all but never even thought of it while thinking up what names should be on the poster and what font would look best and where could we get a big one made etc. etc. I apologize for our D'oh! moment. We sort of thought people would think our posters were awesome. In retrospect I think we missed an angle. :)
