Got some great news, everyone.
Today I started playing with a beta version of the new Wordpress-compliant Montezuma. My devs have been working hard to get it to a place where the old settings are portable to the new version, and as of today we think we're finally there. Just gotta debug it thoroughly and I'll be making an update in this thread.
Anyone wanna be a beta tester? If so, the most up-to-date version of the beta can be downloaded by clicking here
