HI @simoncwsu and @Creatiboom!
I had accepted 4, including your two, earlier this morning. Thanks for posting here as requested! (Sorry, as one of the 4 was quite old, like 19 hours before, and could've been one of you; I'm not sure, and must've missed that one last night. The other 3 had about an hour wait.)
Just accepted two more now, too. Still thinking about splitting off this into an accept 2.2 collab. invites topic, but haven't found the time yet; hopefully this weekend! update: done on Oct. 2nd
