There has never been a full English translation of the song (the only translation is a partial one done by those who've fansubbed the anime). However, I am saving up to get translation commissions for all of the songs, which I'm hoping to have enough money for it by the end of Summer.
Hi Chimera-gui. I approved your request, so let me know exactly what you mean by banner. If you're talking about the header graphic that is uploaded via the theme designer, please link me to the image you want to be used, and I'll crop and/or resize it as needed.
As I posted on the request page, the uncategorized pages at Digimon Wiki will need to be categorized before it can be approved. There are a lot of uncategorized pages there, so if you don't want to wait that long, and if you're talking about the header graphic, I encourage you to try it yourself. 471 x 115 is the ideal size for the header graphic, but you can upload an image of almost any size, and the theme designer will resize it automatically.
I wanted to add pictures into the infoboxes of characters who don't have them yet. For example, I found this one for Mariko on the internet. What is the policy on them? Can I also use screenshots from youtube videos?
It's mostly about the Japanese version since that's the original and there's more of it (ex: The English manga translations use the original Japanese names, the 4Kids English dub only covered half of the the anime series.). However, every dub has it's own page (working on some info for certain pages though) and trivia from all known dubs is present in character bios and weapon pages.
Because this wiki is suppose to display information that's accurate to those viewing the show. Despite blue and purple hair looking black/normal to the anime characters themselves, saying that Zakuro's hair is actually black is inaccurate, since her hair is obviously not to those watching. If you used the reason you've just said, then what would be the hair colors of Ichigo or Retasu?
I said that Zakuro's hair was black because in the manga, Minto calls it "raven", which is often used to describe something of black color, and never used to describe something purple. I highly doubt Minto would use the wrong word to desribe Zakuro, so I said in the infobox that in the manga, when she was untransformed, she had black hair.
