Yeah, a diff tool would be good ??
Let’s se… in wp-admin, there was the install, post, profile, auth, admin-header files at least
the functions file in the includes directory and the wp-login file also had a lot of little tweaks.
generally I changed the following WP -> phpBB attributes:
user_login -> username
ID -> user_id
user_pass -> user_password
Also phpBB stores passwords already md5’d, so changed login a little for that.
phpBB also doesn’t have nickname, firstname, or last name, so when I get around to modifying that, I’ll probably change wp to just use username (formerly known as user_login) for everything
