Yes. Anything you can run on another HTML page or on your blog should work just fine. At a base level, Business Catalyst is like any other web hosting platform.
I was pulling my hair out trying to sort the back end of my clients CMS when I watched a webinar with Karim Ardalan, it was on using Adobe Muse and Business Catalyst, I have just started using this system with my clients and it was a great watch! After the show I sent Karim an email asking some pretty technical questions about the problems I was having. And without any hesitation Karim got back to me and knew exactly what the problem was with a solution in tow! I only have great things to say for AID+BC and Karim himself, Thanks to AID+BC for offereing such a knowledgable and friendly service!Aaron Grieve, Feature Design
