Do you realise how many WordPress installations running out there are running on old versions of WordPress? There are many out there and being on an older version exposes you to different exploits and other baddies out there. Upgrades are like vitamins for WordPress, you need them to stay healthy. Newer versions of WordPress even have an upgrade functionality built into them, so there’s no reason why you shouldn’t do it.

So, check out the version of WordPress you’re on. If you’re not on v2.9.2 at the moment, then you need to upgrade. If you are, it will let you know when there’s a new version out!
