Being able to register at VE is not a major concern. What interested me was the blocking from the registration since I am always curious to drill down on Internet issues. One restriction is the use of a VPN, which I do not use. The other is the blocking of my public/external IP address. VE strongly recommends using a "conventional" Internet connection. What is "conventional"? Simply a hardwired connection?
VE needs to strongly address their website structure. The creation of an external IP address is dictated by the ISP and can be influenced by the use of a WiFi router (which I use). Of the many, many, sites I have registered with I have never encountered such a restriction. So, the VE site is, by far, not even close in importance to altering my Internet configuration! Not worth the bother.
