The PG-13 part of petnaming is already covered in the site Rules. But New players would like to know how many characters they are allowed and what kind of characters they can use. I've been playing for eight years and have some really long-named pets, but even my know-it-all self doesn't know for sure the actual answer to this question and a number of other users who hang out in Help & Questions sometimes seem not too sure either.
It would be helpful if the Frequently Asked Questions and Answers had an answer to these two questions. It would also be helpful if the PG-13 part of the Rules were iterated in the FAQ in the create a pet section.
Good idea! I have no clue how many and what characters are allowed. It would be nice too to point out that you CAN use spaces, which people might not realize.

Amber sure does make everything better. with that note being added, I don't think it needs to go in the FAQs. I think on the adoption page is a better spot for it too :)
LOOK AT YOU BEATING ME TO POSTING HERE hahaha.
But yeah, tomorrow I have plans to add a note to the top of the page of when you go to name your new pet. I think it'll be a lot better there (and maybe on the page where you can change your pet's name?).
I'm working on a newbie FAQ page (god it's going so slow ugh) but eventually I'd like to have the FAQ on the help page rather than a board on the forums.
