Congrats for buying the .net domain name. I've used exch.net in Tor it redirects to your onion site. What's the plan for your existing exch.cx name are you phasing it out ? It doesn't look like a good thing if you're going to use more than 1 domain address.
It is currently redirected to the .net domain to make the transition as safe as possible. It is certainly best that eXch continues to keep the old .cx domain in its control and not risk leaving it to scammers, as happened with the old .cc domain, which was only recently suspended.
