I am SirBlaze, an admin for the Sing Wiki, which is for another Illumination film and a wiki that is affiliated with this one. I'm here to ask you (and the rest of the Despicable Me Wiki administration) for permission to ask Fandom for a particular request which relates to this wiki, so please allow me to explain my request to you first.
On the Sing Wiki, we use "singmovie" as our primary URL prefix. I've noticed that upon entering the URL "sing.wikia.com", I am redirected to this wiki instead. However, we would like to utilize the latter as one of our redirect URLs.
On behalf of the administration and users of the Sing Wiki, I would like to ask you if it's okay that I ask Fandom staff to make it to where the URL "sing.wikia.com" redirects to the Sing Wiki instead of here, so that users aren't confused and are directed to the proper wiki for information about Sing.
I'm not sure if you're the primary admin of this wiki, but I would like for you to discuss and review this with your fellow admins so a fair, mutual decision is made.
If a decision to allow me to go through with the plans is made, I will link Fandom staff to this thread (and any other necessary threads) as proof of your decision.
Thank you very much, and I hope to receive an official decision soon.
Now that we mark Sing Wiki as an affiliated wiki since it's well-developed, however, we DM admins were going to merge all IE wikis into one (as I said before, there was another Sing Wiki [w:c:sing], which was abandoned, so I asked the staff to redirect that one to here).
The policy was first mentioned by AwesomeOrange indeed, but I am not so sure whether he still insists the plan now - the three wikis start to develop nearly independently.
So my opinion is yes, it's time to give back the URL because it seems like the merging is not feasible at present time. Waiting for the bureaucrats' answer.
