''Admin''

When you register a forum or create one you will notice that most of the time that the username ''admin'', so when you've done creating the forum do you change the name as do you think having the ''admin'' username a risk to hacker's, do you think that hacker's don't think at all but just would love to hack the username ''admin'', but someother member's have discussed that when you view member list's user number is fairly number one to get hacked, so that's one of the exact reason's I have disabled memberlist to prevent from hacking so what's your thoughts?
