Propose a user group: `Admins of NodeBB-powered sites`

[xinbenlv]

Since community.nodebb.org are for discussing the platform of NodeBB, it probably make sense to have a group that is whoever has a verified nodebb deployment and as admin. Having such group will help motivate more people to ask questions, help those site admins and also a promote a culture of community target: the "user" of NodeBB software itself: the site admins of NodeBB.

I checked the group and it seems it doesn't exist yet.

WDYT?
