We have been able to use Captains Up for nearly two years now with our members. A lot of people I know use it, so there is a good amount of data about usage, but we haven't noticed any particular issues with the software. It's not perfect, but we're happy with the way things are going. If you're looking for something that can help manage your community better, look into this program! They do a great job at collecting all the metrics you need to get started, but they don't really provide much in the way of support other than a few FAQs. The biggest benefit has been the ability to monitor and keep track of all of our activities on the site. Our membership is up by an average of 20% per month since starting to use Captains Up.
