grow your wiki
Welcoming new people to a community is a great practice of openness. It demonstrates a vibrant community that wants to bring new members into the fold and help them become active contributors.
When someone has shown up to your wiki, you add information to a page they might see in the future, quite often their user page or the home page.
Welcome to this wiki, I noticed you added information about x, that is great! I made an edit to the page as well, what do you think about that?
