Before the change i could allow my friend to be set as a coowner of my games, so that he could edit the hub and the like. How do I allow him to do that now? is this even still possible?
Good question! I don't see the functionality any more. It looks as though it was either omitted, deliberately removed, or it just slipped someone's mind. I'll ask the staff for you.

Thanks, i'd really appreciate that. would you mind telling me what they say?

I was going to tell you anyway! =)

According to Tom:

"It's just temporarily out while we transition the remainder of the site. That was part of the old C++ behemoth hub."

So it should be coming some time within the near future—I'd guess up to 2–3 weeks—but until then it's nowhere to be found. Sorry!
