MinecraftSkins.com, also known as The Skindex, is an online archive made for -- what else? -- Minecraft skins. Without an account, you can only download skins from the website, but WITH an account, you can vote skins up or down, comment on them, add them to your Wardrobe (i. E. save them for later), and, my personal favourite feature, use the site's built-in skin editor to make your own and upload them onto the site. There's not much I have to say about this site, so let's just split the review up into Pros and Cons:
Cons:
Trust me, there aren't many. The first con that comes to mind is the extreme lack of user-to-user communication. It's EXTREMELY difficult to get more than one or two votes at all on your skins, and actual comments are even rarer. Even then, the OP rarely responds to you. I'm the type who's a total loner, offline and online, so I don't particularly mind, but to each their own.
My second complaint is the somewhat difficult-to-use Skin Editor. Its UI is fairly simple and straightforward, but the buttons to the left (Undo/Redo, Eraser, etc.) are VERY unresponsive, at least for me. And the Undo button undoes your error(s) one. Pixel. At a time. If you want to undo a big chunk of your skin but not reset it completely, then expect to be there for a while, especially thanks to the fact that the Undo button is prone to being unresponsive as I mentioned prior. I don't know if it's an error on my end or not, but the "Mirror" setting tends to turn itself off at random. It's difficult to explain what it does out-of-context, but I find it to be necessary if you want to finish your skin in less than half an hour.
The "Fill" setting is also a pain if the arse to use. It's pretty straightforward, it fills entire sections at a time instead of one pixel at a time, but if you've already drawn on a section and use the Fill tool on it, intentionally or otherwise, then it will cover up everything you've already drawn on it with that single colour instead of just the pixels that haven't been coloured-in yet. And, when Undoing that, I've had it glitch out and pretend the use of the Fill tool never happened at all (i. E. it refuses to reset it, so I have to redraw EVERYTHING).
My final complaint, more of a nitpick really, regarding the Editor is the fact that there's no way to know which side of your skin is the front and which is the back. It's a 3D render and you can turn it around to draw on the sides, back, bottom, top, etc., but, on more than one occasion, I've had to reset an entire skin that I put my blood, sweat, and tears into because I drew everything that was supposed to be on the front on the back. If I had a penny for everytime I've seen someone upload a backwards skin to the website, I'd be the richest person on Earth.
Now then, onto Pros...
Pros:
Well, let's see... there're a lot of high-quality Minecraft skins on the website, all of the skins on the website are completely free to download, you can download and/or upload as many skins as you want, the entire website has a simplified design but it's very user-friendly, the site's community seems pretty friendly whenever they're not ignoring each other completely, and, my personal favourite, there aren't any features locked behind a paywall. I'm sure you've seen 'em before: the websites with "Premium" accounts, where they lock half of the site's features and blatantly restrict what you can do behind a monthly paywall (it's NEVER a one-off payment). DeviantART and LiveJournal are two examples (IIRC). Luckily, Skindex isn't one of them.
All of these Pro's are pretty self-explanatory I think, so I won't go into depth with 'em. Howeer, there is one feature I would call a... Pron? Cro? It's the ability for any user to edit the skin(s) you upload and upload it themselves. I've never done it, so I don't know if there's a "Originally Made By____" somewhere to prevent the user from claiming it as their own, but yeah, it feels... dangerous. On one hand, it allows you to fix an error for somebody, make it look better, and generally help them improve it. On another hand, however, people could easily claim it as their own since there doesn't appear to be a "Date Uploaded" anywhere, or they could edit it slightly and claim the "new" one as your own without giving you any credit for 90% of the work.
Don't let the aforementioned feature scare you away, though, this is mostly hypothetical. I've seen friends editing each others' skins, people asking prior to doing it, people blatantly telling people in the description NOT to edit their skin(s), and the complete opposite (people encouraging others to edit theirs). So, if there's been skin robbery occurring on the website, I haven't seen it yet.
I'm giving four stars instead of five because of the Skin Editor that is in DIRE need of improvement; if that's fixed, then I might change it to five, but otherwise, the site's pretty cool. I may (or may not) review Planet Minecraft, a more popular MC skin website that also hosts mods for the game, later, but until then, just thought I'd give the Skindex a fair review. They deserve it. Thanks for reading!
