Hyphenation for Movable Type provides automatic hyphenation of your text based on OpenOffice hyphenation dictionaries.
Automatic hyphenation is very useful if you often use left-aligned or right-aligned images with text flowing along the side of the image in a narrow column. With Firefox 3, hyphenation is now displayed on all major browsers.
You can have Hyphenation for Movable Type hyphenate all of your text, or just selected portions of it. You can also use multiple dictionaries if your blog contains entries with different languages.
