Have not conversed with the rest of the team, but, personally, I'm not opposed persay to AI, but would certainly put much higher value on hand made banners – I feel like AI lacks creativity, style? If that makes sense, but also If someone can make a decent banner with it I'm not opposed. Size wise, I'd probably shoot for something like 1000x500, though of I can downscale stuff as needed. 2:1-3:2 ish, other communities have banners to see (two ones I've quickly found is !green@lemmy.ml and !mechanicalkeyboards@lemmy.ml)
This is more of a support question, !lemmy_support@lemmy.ml , welcome to this corner of the fediverse though!
Instance admins can promote users to be moderators. Such is the case with lemmy.ml, where we have !community_requests@lemmy.ml. Future questions should be at !lemmy_support@lemmy.ml
Eventually there will be an automod to remove subscribe pending posts. Next step is to code an automod :)
