The error is telling you that by the time the "to" field of Message is
processed, User already has a "messages_received" relation. Yes, the
message is a bit misleading, since you already have a related_name field,
but what it really means is you need to specify a related_name that doesn't
already exist for User. What is in ridgemoor.msg.models? I'd guess there's
another model with a ForeignKey to User specifying a related_name of
"messages_received". Do you really need two models with this relation? If
so you'll need to specify different related_names for the two.
