It is so fast. macminiosx announce v0.30 of PostTwiOAuth plugin of MovableType is released.
It is better than the old v0.21. More features, acutally I did not use them. Say Google Analytics, etc.
Here if you installed v0.21 before, you have to remove the whole folder and ftp v0.30 files under plugins folder.
Still need to change retweetmaker.cgi to 755.
Not just replace the old one, you still need to re-setup the token of it.
Here is the link, you can download zip file or gz file there.
