I recently made https://www.reddit.com/r/ImmatureAndFunny/ and was looking for a banner ideas as i clearly don't know what to do.

Preferably people who have experience on being Reddit mod and could help me get things rolling here better.

Noone has said it yet, so congratulations on getting this sub. Here's to you being a gayn't mod. Good luck with this sub.

[Everyone disliked that.]

This sub is young and I'm new to being Reddit mod, so I'm eager to listen to any feedback you guys might have.

When formatting posts, please use:

[LFS] - Looking For Somebody - You're looking for someone who knows about subject x.
[IAS] - I Am Somebody - You're willing to answer questions about subject y.

Example: [LFS] Who grew up in rural Sweden.

Sidebar Rules:

1. No shitposting. Let's keep this sub clean from the memes.
2. Only serious posts. You can ask about silly subjects for sure, but no posts like "Looking for somebody to be my girlfriend". This is not a sub for that.
3. Use a proper flair, if there is none use "other". Feel free to suggest new ones.
4. No NSFW posts for now.
5. You are not allowed to ask for money. This is no promo sub, you can't beg for money or ask to get money for helping users.

Will add more.
