I purchased this extenions a couple of weeks ago for a community site that I'm building. I'm a very novice user and am pretty much stumbling my way through this whole process. I was able to install the extension but didn't quite understand how to configure it, so when I contacted OSE, they configured it for me without hesitation. Every question that I asked was answered in a timely fashion and they were very much willing to assist with the product...to me, that speaks volumes! The extension seems to be working perfectly so far....no problems.
