All fair points, thank you for the insight!
As far as the listed site functions are concerned, those are all yet to be completed. We're looking for someone to do them.

I'm aware the user level system can't be implemented until all of those features are complete as well. Other, unlisted, features like forums and things are already complete.
The demo wardrobe would be the basis of what we want our wardrobe to be. (Just implemented as a wardrobe feature with minor changes, like showing item art of clothing pieces rather than just a small picture of the clothing file (like it does in wardrobe). Also perhaps adding buttons to move clothing layers up and down because dragging them around isn't working for everyone and once you get past a certain point with just so many clothes, it breaks the box and those items can no longer be removed. (Of course we could also remedy this simply by adding restrictions on how many items a character can wear, which is probably something we should do at some point anyway.)
And yes, good point about the separate file explaining these terms. It didn't occur to me for some reason. But yes, Cravary is a pet your character can collect. Craviary is the bestiary in which said pets are logged. Pens are just called pens, to keep that simple at least. I will have to discuss with the co owner about the names because they are pretty attached to them.
Pet breeding I left a bit blank for now. But we are wanting a more simplistic take on it, as our pets can pass stats but they don't have markings, genes, etc. It's more like breeding a Pokemon, than breeding a dog or horse. Definitely less involved than a lot of breeding systems on most other games. (Or, I think so anyway!) But we intend to get a proper layout of what we want that to look like as well.
Pet scavenging missions are basically, a quest will appear for you to select 1-3 cravaries with specified 'skills'. So those skills could be something like Stealth and Agility. It will denote how many cravaries are required for the mission. (So if you need 2, it could be 1 cravary with both skills + 1 extra cravary, or each cravary could have one of the required skills.) You don't need to bring anything to the quest or 'turn in' anything. After whatever amount of time the quest has you wait, you'd redeem rewards for having fulfilled the quest requirements.
