I've read about the brute force attacks and understood, from the official write-ups, that it is no great problem. No lazy passwords with me!

Even so, I've installed this plug-in and see that there have been attempts against my blog, none of which have been successful.

Perhaps this plug-in needs a little more publicity, just writing that there is a problem - as others have done - and playing it down is not the answer. Defense is much better!
