Sure!
Though I would like to nail down the setting here, ideally we can fit it all into a single site setting with multiple options.
Would like to first get a good spec going. Some questions:
- What about reactions and plugins?
- What about user profiles?
- What about signing up with new accounts?
I worry also about allowing too much fidelity here.
Maybe a simple maintenance mode on/off and allowing admins always to bypass, is good enough?
