I have never written a Joomla extension review before but I feel it's necessary now. Up till now, I purchased Open Source knowing it was pretty much "as-is" or required a level of php to hack your way to satisfaction. The JCS team helped me configure the software at a very reasonable charge. The software does everything I want by limiting access to certain articles or components to subscribers only while having the balance of the site being Public. Thank you very much Sergey!
