Hi, The third time's the charm - I've refactored the bejeezus out of babycart, dusted off my OOP perl books, and built Blog::SpamAssassin.
See http://www.cynistar.net/~apthorpe/code/babycart/Blog-SpamAssassin-1.3.tar.gz for details. This distribution contains an actual perl module suitable for inclusion in perl-based blogs, wikis, and message board systems, plus a refactored babycart standalone script and proof-of-concept PHP code. I still need to hack on Wordpress, but all you Movable Type hackers can get started. Code and documentation review, test cases, and contrib code cheerfully accepted. I'm not sure Blog::SpamAssassin is the best name; if I can get a decent name and some code/doc review, I'll post it to CPAN. Have fun, -- Bob Apthorpe
