New development version released of BlockIt. Version 1.4.3a comments: 

Added some logging for MySQL. It'll help me debug emails questions. Thanks to Alexander Garzon from PHP of Venezuela Foundation for a new rc.blockit2 file in contrib. Miguel Angel Flores added the "UseChain" parameter by default it'll be set to BLOCKIT but now thanks to him you can set it to whichever target chain/table e you wish.
