I have a couple of questions...
I was wondering how the merge system worked? Because I assume it must update various tables containing a member's user_id to match the chosen member's user_id?
If this is the case, would it be possible to use a similar system to change a user's user_id on it's own?
My main question: If I was to create a brand new member, with no posts, etc. What tables would need updating to change the user_id?
Reason being, I'm creating some staff accounts and user_ids from 2-7 are available, so I would prefer to use these ids for easy reference instead of having higher, easily forgettable numbers.
