I’ve just been trying to figure out how to trigger some action on User creation. For example, imagine you want to make sure that a new user automatically follows some important folk in Chatter! ( signed up yet?) It turns out to be a little tricky because the User object is a little special. The documentation states that some objects “require that you perform DML operations on only one type per transaction” – the User object is one of these objects.
