I'm still pretty new at it, but I've started work on a Toyhouse account ^ u ^
It's so cool, the site layout has exactly the features you need!
I'll probably only keep quad designs on it because my other OCs are for personal projects
Once I have some free time in future (very distant future) I would love to do some quad trades, so this would be a helpful resource!
Here's me with my squad, please add me if you want!
