XenReviews is a successful crowdfund project that I and a number of other people invested in. XenReviews is developed by @Jeff Berry and @Daniel Hood

XenGrid is currently in beta phase. A new update and public release in the resource is to be expected in the near future. More information on https://xenreviews.com
