Looking back at your comment on my Message Wall not so long ago (which is extremely helpful and I'm still trying my best to stick with what you have said) the following I can quickly summarise here in regards to the new wiki (and to make your decision a bit easier):
• As the Haikyuu wiki has at least two admins who review the request, I thought I might ask you since you seem to be the one who is more active. I was also planning to get Chan involved, but I didn't want to bother her as well especially since the both of you are very busy.
• Yuri on Ice Wiki is still fairly new, so that will be the main deciding factor as to whether we would accept it or not. It is based on the new anime which came out a few days ago, so there isn't many contributors but the pages do seem to be quite informative and up-to-date. The anime seems to be quite popular as well, so I think there would be more users who would contribute and make the wiki more established and user-friendly.
I'm sorry for bothering you, but I thought it would be best to ask for your opinion as to whether we should affiliate with them or not :)
