An xkcdCon is a gathering of people who read xkcd. Hypothetically, anyone from anywhere in the world can attend one, so anyone anywhere in the world can host one, no matter how large or small. The only requirement for it to be an official xkcdCon is that it be called it be called The (i+1)th n-Annual xkcdCon, where i is the last one listed on this page. You must also, obviously, list yours on this page too. Note: n is technically a variable (as in bi-annual, tri-annual), but since anyone can host any number of xkcdCons anywhere, n is non-finite. Leaving it as a literal is the custom.
