I decided to use the Site Wide Text Change plugin to change where Wordpress was mentioned, but there are a few places where it isn't a good idea to change that.
An example of that would be the import file section. My site is Hants.me, so I changed Wordpress to that, but get the following:
WordPress Import posts, pages, comments, custom fields, categories, and tags from a Hants.me export file.
It would be best to still say:
....and tags from a Wordpress export file.
