How do "private messages" here work?
I sent a message to someone, but it is stuck in my "outbox", rather than in my "sent items" folder.
Does this mean they have not received it? Or is this a normal part of the process?

[btw, there seemed no appropriate forum/subforum for this topic, so I just put it into "Countdown - General".]

Outbox means it hasn't been read yet.

Ah! That explains it then.
He is not the most active forumite, so it might be a while yet.
