I merged a user that had his original account registered in 2001. The newest account registered in 2012, but somehow even I wanted to keep the old account, it now state he registered in 2012 and have only posts linked to him posted after 2012.
This is one of the oldest active member we have, and it's a pitty he lost his older records.
Is there any way to edit his register date and get his 300+ older posts linked to his active account?
