@VoroVoice I wish I could give a straight clear cut answer. Best thing to do is sift around the Artist news section (even in the General Users tab). Usually someone is looking to collabwork project.
Collabinate thingy link here too : https://www.newgrounds.com/collab?type=1
There is a Winter festival event coming up soon that you might like as well.

Thank you, kindly! Fortunately, I've been on forums before but its definitely been a hot minute. I'm mostly just trying to figure out how to dive into making awesome things with people, haha. I don't suppose you happen to have any advice for that?
