Ah forgot to mention about one more thing. You can test CyberSEO Suite absolutely for free at
http://rbbloggers.com. The only condition: you must be registered as a
Real-Bucks.com webmaster.
Of course "Morphing RSS Host" and "Standalone" modes are disabled in WP-mu edition of CyberSEO Suite, but all other features work in a same way as in the commercial version of plugin.
