Community
There are several places you can go to "meet" other people that use Lua. A good starting point is lua-users.org, a collaborative meeting place built for and by Lua users. One of the focal points of the Lua community is our mailing list, which is very active and friendly; it has over 2000 subscribers from all over the world, including several Lua experts and the Lua team. Other meeting places are Lua BR, the chat room, and the forum. Lua is also frequently cited in usenet newsgroups and in stackoverflow.
Part of the Lua community has met in person during a workshop in 2005, 2006, 2008, 2009, and 2011. The main goal of this series of workshops is to allow the Lua community to get together and meet in person and talk about the Lua language, its uses, and its implementation. Another goal is to help spread the word about Lua to industry and academia, taking advantage of the location of the workshop when possible.
If you're interested in attending a Lua Workshop in 2012,
please
sign up.
You can contribute to the community in several ways: answer questions about Lua (in the mailing list, in the chat room, in the forum, in stackoverflow, and elsewhere), collaborate in the lua-users wiki, answer our survey, add a Lua logo to your web page, tell us about third-party sites related to Lua and papers and theses about Lua, write tools and libraries for Lua, and add them to LuaForge.
You can help to support the Lua project by buying a book or by making a donation. You can also help to spread the word about Lua by buying Lua products at Zazzle, CafePress, and Fibers.
