I saw your previous thread when you first introduced yourself as an alternative to Preev.com which is offline.
Although I don't know when they
(the developer/owner of preev) fixed the site but preev.com actually is now working
(i accessed it by the time of writing), but it doesn't have secured
(https://) connection for now.
On the site, there is no contact us page or link or even a social handle so we can message them and ask them to secure the site
but they renewed and extend their domain up to 2025
Domain:preev.com
Registrar:Name.com, Inc.

Preev is one reliable tool and they have established their platform since 2011 but I'm ok with adding PNNV because of its new features and they keep adding more to the benefit of the community.
