I've been doing lots of research on SEF extensions. Tried them all and although none of them is perfect 10, I have to give sh404sef thumbs up for being the most complete and workable extension of this kind. It took me literally around 45 mins to get it working. I guess I'm also lucky because the rewrite_mode and .htaccess file is compatible with the hosting server. The documentation is a bit unorganized IMHO. However, I was able to find information I was looking for. Thanks for an awesome extension. By the way, I'm also a subscriber of JCalPro and have high respect for it as well.
