RedonPress is a WordPress plugin designed to provide integration between WordPress and Dreamwidth (or other LiveJournal-based blogging tools).
The code is based on a plugin called JournalPress, originally written by Alis Dee. JournalPress was a good plugin, but it hasn’t been updated in six years. I also found the limitations on avatars irritating (basically, it excluded all avatars with apostrophes in their name). So I forked it.
