how do I tell Mlp wiki that I found some of their lost/missing files.

I was going through the data.MLPmerch.com site and I found ponies such as lucky that were missing (info/files/pictures) in the MLP wiki so I'm going to contact them so I can tell them to upload it. How do I do that? Do I email them or something because I cannot log into the wiki because because it's like only like very known people only.

I submitted a photo for their database, and to do that I just emailed it to "submit@mlpmerch.com".
