I wasn't planning to work on any of those anime titles you listed in the near future so go ahead with those requests. As long as the pics are good quality, one of the mods will probably be more than happy to complete your requests.
I haven't worked on a lot of anime, but I'd say that those would be under TV shows. As for the second, you're better off asking one of the admins for that, as they're the ones who actually decide that kind of thing. Best ask a few of them, actually - different opinions can be very useful - but be sure to include Jackson H. He's the big anime guy on the team.
Hey Marty, those sound like interesting topics and ones that users might find helpful with the right descriptions and instructions. Feel free to post what you want in the 'General Chat' or 'General VA' Discussion forums.
As long as your images are within the correct cropping dimensions and size restrictions, don't worry, they'll never be "too good".
As for the Idea Input forum, it was removed because we're doing some streamlining in the forums for 2020.
I'd say try this one with a bit of tact. Give them a few days, and if they don't respond, send a friendly reminder. If there's still no response, you can try a visitor message, but also consider trying someone else. Just bear in mind there might be reasons they might not be able to answer you right away - especially at this time of year.
It's also important to not keep hitting someone with messages, or presuming a lot about their work or schedule in the text. I say this because I recall someone who did that to me before I was a Mod, and it did not endear them to me at all. So best to be patient, and keep a close eye on what you're saying to them.
I don't really do the programming side of things, but I can give you some tips regarding file sizes (something I had to learn the hard way). Ideally, your images should be 210x240 and less than 20KB (officially states 19.4, but 20 is better as a guide). This means we don't have to resize them at all and keeps the integrity of the original image. If the image is over 20KB to begin with, reduce the quality just enough so that it fits the allotted size. This is all for character images, though - there is no size restriction for posters, banners, logos, or credit images (just that you stick to the stated dimensions for each). As long as you stick to that, it means we can just download and input them straight without any adjustments.
Wasn't sure if it maybe made it easier for whomever has to add everything. Don't know if they have to crop it all themselves or the site does it automatically.
