Hey so I just noticed while going through the recent images, and uploading my own that there has been a lack of using the categories. I'd just like to say that they are there so that this wiki can keep its images organized and neat. While I can't enforce this as much as I'd like to, I would for people to wary that we do have organized measures on this wikia.
So here is a very quick guide to the categories used here.
Chararts - Now you don't use this category as it is the master one, and organizes the sub-categories. But those sub-categories are the ones that you should use. Each age bracket of character ha a different category for its respective charart to fall into. For example, File:Spiderstar.adult.png, is given the category Category:Adult Images and nothing else.
Life Images - This one should be self-explanatory. Once you upload your cat's life image, just quickly pop this category onto it. It's really just there so that its organized, and for people who like to look through them sometimes.
Also, I'd like to mention that our character template adds all the categories for you. All you have to do is fill in the required sections to receive such categories. And for reference, you will have to write MCA to get the appropriate category for a Medicine Cat apprentice. That's all I've got for now. But if you do have any questions, or would like a better explanation, just comment on this blog and I'll get back to you.
