TikiFest is a tradition in the TikiWiki community. A TikiFest is when there is a meeting between at least 2 TikiWiki contributors that don't meet usually. This is an occasion usually for drinking adult beverages, getting laptops out and coding wildly in group sessions, discussing about wiki technology and culture, etc. depending the mood and context. It is a great opportunity for Tiki users and Tiki power users to meet some of the developers and learn more stuff 😊
Those that can't attend physically will participate online (bug tracker, chat, forums, mailing lists and the wiki of course)
