Openmelody is in BetaFollow @ggarron
Openmelody the fork of Movable Type has announced some days ago the release of its Beta version.
Actually it may not be considered a real Beta as the Alfa was based on Movable Type 4.32, so it has a lot of background and stability.
The Opinions sub-blog of this site is hosted by Openmelody.
So I am already planning the upgrade.
Check the Openmelod blog for more info.
