There are several places you can go to meet other people that use Pelagia. A good starting point is github.ocm, a collaborative meeting place built for and by pelagia users.
One of the focal points of the Pelagia community is our issues list, which is very active and friendly; It has multiple subscribers from all over the world, including several Pelagia experts and the Lua team.
Other meeting places are the chat room and stackoverflow.
You can contribute to the community in several ways: answer questions about Pelagia (in the mailing list, in the chat room, in stackoverflow, and elsewhere), collaborate in the Pelagia-users wiki, answer our survey, add a Pelagia logo to your web page, tell us about third-party sites related to Pelagia and papers and theses about Pelagia, and write tools and libraries for Pelagia and add them to Github.
You can help to support the Pelagia project by buying a book published by surparallel.org and by making a donation.
You can also help to spread the word about Lua by buying Pelagia products at surparallel.org.
