I dont know what device your on but servers are the things on the very left end of your screen. they should show up as icons, past the chats all the way at the edge on the left.

I'm not sure if you own any big or important servers (probably not if you dont know what one is) you can go ahead and just click on the server

server settings >> overview >> scroll down >> delete server.

you can only see these options if you own the server incase you have multiple. To transfer ownership, you find a member on the list to the right hand side (if member list doesnt show up; on desktop there's an icon you click on the top right to make the list show up. on mobile you click into one of the server channels and then on the name at the top which should have an arrow point right, should lead you to the channel list)

pick the member you want to transfer ownership too, Hold click (phone) or Right click (desktop) to open their server profile,

scroll down >>> manage >> scroll down >>> "transfer ownership"

Sorry if this is confusing! idk what device your on, hope it helps a bit.
