Jammy was almost all knowing when he was community moderator
I’m not sure how large your community is but from the outset my advice would be to choose moderators from members with a high trust level already. Having a moderator team is about quality not quantity.
Key word here is ‘wanting’
I’d thank them for expressing their interest in wanting to help the community but since they are new they need to prove that they are trustworthy, basic things like being around for a while, actively participating etc. Therefore, I would be very reluctant to give them a category moderator role - I probably wouldn’t.
Notice that here on Meta users that are TL4 and not in @Team are rare. That is not to say that everyone else is untrustworthy and doesn’t want to help, but in your community, the circle of trust should be tight if that makes sense.
That is true
I’m not sure I fully understand
I’ll leave you with some great points by @Tris20 made on another topic.
