Running WP 1.5 (downloaded today - upgraded from one of the 1.5 nightlies).
Have just trialled plogit, vagablog and hblogger on my palm.
plogit couldn't do anything - just gave a parse error - the other two have correctly connected, retrieved a list of blogs (one) with the correct name - but both give a parsing error on submit post.
Anyone got a palm blog program talking to a 1.5 WP blog over xmlrpc? If so - which one?
