Pellet heads is back up and running, but it's definitely very slow. Only a handful of people contributing to the forum.
There's a couple moderators that are on all the time, one is "low slow joe" or something like that. I suggest sending him a PM.
The biggest draw to PH for me is the vast amount of info, recipes, that are archived.
Before the past owner passed, PH had a lot more members than pelletfans has now. I suspect a bunch don't know about PF. And when PH went down for several months, they found a different avenue for smoking/grilling.
