Forgive me, I am a babbler, and I must babble point by point given my own experiences.
This seems to be a list best fit into a discord server, though I may be wrong. Maybe that was your template or maybe it's a coincidence. Either way, I'll use that as a frame and extrapolate to other community types.
1. Certainly, a basic list is necessary. It's also necessary to have configuration done properly and the rules presented cleanly. Make an effort to be professional and you can be on your way to minimizing drama, which is really the point of all this, ei?
2. How this works and how necessary it is depends on the type of community. I raise you another point, something perhaps in place of this that is more directly useful - have a point to your community. Stand for something, represent something, have an identity. A general server for whatever is probably going to drop a lot faster than a community with specific drive and purpose.
3. You do not need "moderators, administrators, managers, owners, workers". It's a common habit to try and overstaff a platform and make too many arbitrary splits, and the result is a bunch of bored staff without enough players. This is especially true in a minecraft server, but often happens on the aforementioned discord example and other communities. What you need is:
- Doing your job as the owner
- Possibly a few administrators to help implement things (needs changing depending on the point of the community)
- A few mods to fill the gaps and expand in number as the community needs them
Each staff rank needs to have responsibility and a clear place in the hierarchy. This goes beyond permissions. They need a point. Having the ranks moderator, trial moderator and helper is completely redundant because trial moderator and helper have an extreme task overlap and usually aren't necessary in split roles, especially for the newer servers that employ this sort of redundancy. With this in mind, you can in fact have roles with near or fully identical permissions so long as each rank has its clearly defined and justified role.
4. Sure
5. Of course, though frankly, extra most of the time is quite unnecessary as short of a password leak (change it when you hear of it and keep on it), most of the time it would be your own fault you get hacked. Two step authentication isn't the best answer. Watching where you type your information and being responsible in the first place is.
6. Not usually a priority, but it is nice to accommodate people should this (rather obscure) need arise.
7. Tricky one, it's really a 'you have it or you don't' thing I'm finding. You're legitimately invested in the emotional stability of others or how to otherwise accommodate the most people, or you aren't, and either way you need to make your way as best as possible.
8. Naturally.
Grammarly has done a pretty good job. The errors I spot are fairly small, though "You need Catagories" is a bit offputting, as well as some other randomly capitalized words.
