Hey, I realise this is an old post, but I just tried to use this script, however I can't see a text box inside the shop page to add my list of items?
The script is enabled on tampermonkey, and I'm using FF. The jellyneo script works fine, however.
You can request the creator of the script take a look at it, but given the Neopets site is in a bit of a state right now with the mobile beta rollout live -- please read our (you need an account to see links) -- many scripts are not working as originally intended.
You may not gain the resolution you're hoping for, but good luck. Please just make sure to make your request politely.
I sent the club a wire stating, "Please accept my resignation. I don't want to belong to any club that will accept me as a member."
