This won’t hurt a bit
And, actually, upgrading to WordPress 2.6 was pretty easy. It’s supposed to be very similar to WordPress 2.5 so users of this site shouldn’t really notice a change. I like to keep my programs updated to take advantage of additional features. Additionally, most updates/upgrades install additional security measures.
I was concerned about the various plugins I’ve installed in this website and how they might interact with the new version. Some of them control how the site looks and others control how the site acts. They look fine so far . . . . If you notice something on the site which looks or acts weird, please let me know so that I can fix it immediately.
