PM System - "Carbon Copy"

[Luke]

I was going through how the PM system works... One thing I can't understand is why in "msg_cc_users" in the "message_text" the member's name is stored there. When the PM is read it seems to go through these and fetch the member ID's... The member ID's are not stored along with it... So it isn't a matter of caching the data...

Because of how it is stored, what happens if the display name or login name is changed? Either it no longer knows who it is anymore, or if another account has this name it will associate it with that ID. Why not just store the member ID's instead and fetch the display name? That way no matter if the login name or display name changes the association will not change.

If you are correct with your findings, you have a very good point, one of the main points of having a numeric ID, along with others, is the ability to relate to a members, something that is concrete and will never change.

Yeah, this makes more sense.
