As the perl hacker/source code reader might be able to surmise, there are a lot of surprises (big, awesome surprises) still asleep under the hood. Some of them will be released with the plugin pack and some later on when I have the time to implement them properly.
Jay Allen released MT-Blacklist 2.0e today. The new version is compatible with Movable Type 3.0x releases but not compatible with 3.1 beta. As the developer of the #1 Movable Type plugin I am curious how the licensing and donation system is working for Jay. Jay asks for $100 per author for commercial use of the plugin and $5 per author for educational and non-profit use. For a 5 author installation with each author using MT Blacklist Six Apart would receive a licensing fee of $200 and Jay would receive a licensing fee of $500.
