You can't delete a Neopet; you can, however, put it up for adoption and forget all about it. Go here to disown your pet:http://www.neopets.com/pound/index.phtmlOnce a neopet has been created, you cannot delete it. Although if it's inappropriately named, you report it to TNT and they'll delete it.
You can have 4 neopets on a single account.
Yes, but the only way is to be the leader. If you are then you need to delete all of the members then o the bottom left cornor you will see delete guild. Click it then your guild is deleted. If you want to leave your guild and is the then just quit leadership located right by the delete guild.

You will have to submit a ticket to TNT, and they will start the process of deleting your account. You will have to prove that it is really you asking to delete your account, not someone who gained access to it. See the Related Links section below to get to the Support page.
There are many sites, one of which is marapets but the site isn't as sophisticated as neopets i think.
Jelly world is not on the map. To get to jelly world go to the main homepage of neopets. Delete index.phtml off of the URL and type in jelly.
