There are two things to consider:
1. Should the introductory post requirement be lifted? We could instead just suggest it without making it a requirement. If we choose to lift this, I can re-add all the people I removed earlier as well.
2. Should the community be kept restricted to members-only? It could instead allow public posts, though each person would be free to make their posts friends-only.
Please let me know your thoughts!
EDIT: This community is open and unrestricted now, so just let me know if there are any objections otherwise I assume everyone's happy with it.
