Lemmy Support

Sorry for the vague question but I'm hoping there's a lot I"m missing. I know I can edit the side bar, icon, and banner. Make the community public or private and there's a "mod posting only" option. But is that it?

Some things I'm wondering about,

• can I turn downvotes off or is that an instance only thing? (fan community, off topic would just be removed)
• Is there any other way to manipulate the community page like backgrounds etc?
• Flair's or post tags? Any community settings I looked over?
• Allowing or disallowing bots (again is this an instance thing?)

I'm fine with what it is, just wanted to make sure there wasn't more I was missing with my options in the community.

Bonus question, besides crossposting and the "new communities" community sections, is there anything else I should do with a fresh community?
