I'm not talking about nickname, but the bog-standard administrator login name of "admin" that WP assigns to every new install. My site's been up for a while, and to add that "extra" bit of security I'd like to have something harder than "admin" for the Administrator account. Should be selectable at install time, IMHO. Standard security practice.
Can I do this by going into the WP_users table and just changing the account name there? Any impacts on current articles? TIA
