In most collaborations you have to be asked in but i do know of one group that I think has an open forum where anyone can join however I do not know the link to it. Maybe ask Heba Elafy or Claire north I think they may have been in one of them that was done by that group. You can also start your own, just come up with an idea that you think others will love hen invite a few people you know and even a few you don’t and see what happens. Most collabs the people in them are friends, that i show the first one originated …with a great idea and a great bunch of cakers to contribute.
