Five days of editing, citing sources, open data and knowledge-sharing get underway tomorrow when the tenth Wikipedia Summit opens at The Barbican Centre.
Dubbed Wikimania, the annual gathering of fans of and contributors to the world’s fifth largest website  will include debates, workshops, meet-ups and presentations by luminaries from the worlds of science and technology.
Wikipedia founder Jimmy Wales will start proceedings with a keynote speech on 7 August.
After the celebrations, the main conference programme opens on 8 August, so if you ever wanted to know how to Grow the Awesome in your Programs [sic], or How to Stay out of Jail and use Wikimedia Commons, you know where to head.
One-day passes are £30, a three-day ticket is £50. Five-day passes, including a pre-conference, are sold out. Around 4,000 people are expected to attend, so pre-registration is advised.
