Things are accelerating - I just got the special offer on XCommentPro (by the same company as XSitepro2). It is a 'piece of cake' to integrate a user comment/rating system into XSitepro2, with full admin suite, social bookmarking, Captcha, email opt-in, moderation and the rest. My first attempt took me less than 2 hours, including the software download. It really is great. See my first attempt here at http://www.ezcookery.com/ .
Next job is to add comments to http://www.sadaffectivedisorder.com/ and to http://www.footballpoolswizard.co.uk/ . Too much to do and not enough time!
