Hello. I have read the community policies and found no such rule that adoption pages shouldn't be reset for new requests (especially as it is five years old and resolved). I'd like to add that adoption request pages aren't the same thing as talk/comment pages, and aren't meant for open discussion between users. So I'd like to request that you direct further communication to my message wall, and not to an adoption page. There actually is a rule not to be disruptive on the wiki. https://community.wikia.com/wiki/Guidelines
If you do find a page detailing such a rule as you mentioned, please post the link on my talk page, and I'll be more than happy to adhere to it.
Uncyclopedia was a wiki completely separate from wikia.com until a few years ago so it works differently. The login names are completely different, but you can start an account there under the same name though if it's available. My name for both mainstream wikia.com and uncyclopedia is Miley Spears, but I had to sign up for each separately.
If you need help, feel free to leave me a message; you may also want to visit the forums or join us on Chat. You can also check the staff blog to keep up-to-date with the latest news and events around Wikia.
