This is officially my first post via the Lekhonee client for publishing to WordPress sites. The hardest part was setting up the site address, but once I actually RTFM-ed I realized I had to double check a setting in WordPress->Writing to make sure the XML-RPC protocol was enabled. Check it out if you are looking for lightweight ways of making simple osts. anything with major pictures or custom layoout should probably be done through the WordPress WYSIWYG. At Original Computing, we use Lekhonee in low bandwidth situations for clients to make sure they have a stable post-writing environment.
and its free (as in beer)!
