I have been creating a plugin for word press, that can publish certain posts to eblogger, using the gdata api. It now supports setting the published date, title, and content, formatted in HTML.
I’ve been quite pleased with it, and will be releasing it under GPL, fairly soon. I just need to build the page for changing it’s settings, which is quite simple, as it only needs the users username, password and blog id, plus a list of the categories and tags to publish.
A future feature, could loop over old posts and post them also, if they meet the criteria, but I don’t really feel it’s worth spending much time on yet.
Oh, and some of the times on older posts will be wrong, Had to setup a timezone offset, so that it got it right.
