I'm very interested in XenForo as a lot of my competitors use forums and i'm looking to compete with this platform.
The only two things putting me off are:
1) VAT - Since I live in the UK, there's no get away unless i register the purchase with my family's details (who live in US) - Would this be allowed? Or do you need my address for personal/verification purposes?
2) Secondly, is XenForo resource heavy? I have a VPS with 8 CPU's, 8GB DDR3 Dedicated RAM and SSD. It VPS currently crashes with high volume traffic on my main website, will it do the same with the forum?
