Basically what is says on the tin. On CGCC we have a couple of questions about golfing language design, one of which partially focuses on what's possibly the most important and hard-to-get-right aspect of it: actually getting users.
Will we allow questions about:
- Building and maintaining a community of your language's users
- Attracting and organizing open source contributors to implement your programming languages
- Advertising or bringing attention to a newly created language
These are slightly different issues from what we normally cover, but I feel like as a niche tag (community-engagement or something) it would be nice to have and not harmful in any way.
