I found an old thread from 2017 (
https://pelletfan.com/index.php?topic=538.0) about what happened to the PH website and I think I may know what happened.
PH is is still an active name.
For those of of you with computers, you can do an nslookup of it and it will give you the IP address, and you can ping the address.
So the name is still in DNS and it is live.
I'm thinking the Burk123 is the owner (or works for) Earth Sense Energy Systems, Inc and just wanted the name.
If you try to go the PH now, you end up at PH (without the S on the end), Earth Sense Energy Systems.
They sell Pellet Stoves and Grills.
