I'm a big board admin who recently paid for XenForo and enhanced search. Imported my VB3 forums just fine onto a test site. I love the look and the features, way better than VB3, and it seems clear the performance advantages could save me a bunch of money. Love the software. However, my feedback as a customer is that I cannot actually go live with it in the present state of no releases. Without the proper cycle of identifying and fixing bugs, from a security and stability point of view it would be irresponsible of me to switch. I stuck with VB3 rather than upgrading to VB4 because I didn't need the new features or the new slowdowns/instability, and VB3 was a well-tested product with a commitment to releasing security fixes well after they stopped selling the product. With a less established product I can't go live with it in a "frozen" state, I have to expect more bugs and it's only safe if those are being regularly addressed. I'd be very happy to go live with XenForo if maintenance was ongoing.
