I tend to get as many people involved in collabs as I can

Isn't that just normal IC interaction, then? What if you do a collab with, for example, 3 out of 4 people—what is that last person supposed to do?

Seems to me that it adds an unnecessary barrier to player interaction. You have to contact whoever you want to collab with privately/specifically instead of just interacting with their character right away in the roleplay.
