My Joomla site is a new kind of auction site www.pegdown.com, and I've written or edited almost all of the source code for the site's components and modules myself. Because of this, integration with many 3rd-party plugins has been a pain. But their customer service has been amazingly patient with me in finding and fixing script errors conflict issues that were causing the Facebook Connect module to not work on my website. Unfortunately, I've decided to discontinue use of the their product for integration issues (my site is very customized & I'm not a very experienced PHP developer). However, based on Cerontek's support alone, I still highly recommend that anyone looking for a Facebook Connect solution take a look at their FBWidgets Joomla extension.
