"Technically, you would only need one Time Traveller Convention"

Someone's organising a Time Traveller Convention, on the basis that if humanity does develop time travel in the future, then a future time traveller would turn up at this event. In fact, as he indicates, you would only really need one Time Traveller's Convention, ever, since the concept of "ever" doesn't bind time travellers.

So I'm doing my part to advertise this event, in the hope of increasing the chances that someone in the far future, if/when time travel exists, will hear about this and pay this convention a visit.
