lorigreenberg,
#1 Yes, it’s under user’s profile. I would set a nickname that is no relation to your username. If the username of an admin account is revealed, then all they have to do to exploit your website is to guess the password in relation to that password.
#4 Change the CHMOD of folders to 711. If you want to listen to others, then set it to 755 and put an index file in each folder. Oh, whoa… We have thousands of folders.
>I would also like to know what is the best way to defend against hacking to our blog.
Patrolling your website daily, twice or three times a day, is the best defense. Most victims aren’t even aware of problems. Many of them are out of reach and ignore our kind notifications. The worst group of webmasters is colleges and universities for that reason.
