Convention

A Convention is a gathering of people meeting for the purpose of discussing or enjoying some aspect of Science Fiction. Typically a convention will have a theme or focus on one or or a few genres of SF rather than attempt to have programming for all of them

Well established conventions will typically have an ongoing name or nickname for themselves (e.g. World Science Fiction Convention / WorldCon, Westercon, Noreascon, Comicon, etc.) that reflect their intended scope. They also will often be numbered as successive similar conventions are held. Naming can be simple and straightforward (e.g. LA Con I, LA Con II, LA Con III, etc.) or complex and whimsical (e.g. Gallifrey One, Gallifrey One: the Sequel, Gallifrey One in 3D, Gallifrey One Goes Fourth, etc.)

Size may vary from a few hundred attendees that might visit a small local gaming convention to over 20,000 that might attend a major comics or animation convention. Attendees may be from only the local area, or travel from all over the world. Adequate hotel accomdations in the near vicinity of the convention site is essential.

A compact site, or at least easy circulation on the site is important. If attendees have difficulty moving around at the convention site, or between their living space and the site, they they will not take advantage of all the features and events. If they anticipate problems, some may not come at all.
