Awesome!
A bit late on this reply, but it's a bit of a funny story how I ended up here.
I can't remember what started my train of thought but I ended up thinking, "I wonder if any sites like Sketch Star exist now?" I did a little search on google, and stumbled across Brush Ninja, and realized that the name sounded very familiar. I did a little search back here on this page, and sure enough, I realize why.
Thank you for all your effort in making this. I'm not sure how much of the group is still active, and I've left this group so I can't create an announcement on this page particularly, but I will try to make a journal entry on my personal account for those who are still interested!
