There is already an alt.hvac pro-series.moderated
It gets absolutely ZERO traffic.
Which, to me, demonstrates that the self proclaimed "Paul & pals professional pricks" have zero interest in an actual forum for "professionals" and instead like to demonstrate their ignorance by picking on anyone who asks a question in alt.hvac.
If they want to use it, and avoid the folks whom they describe as "homeowner assholes", the "professionals" already have an exclusive forum.
Establishing an "alt.hvac.advice" forum will only give the "Paul & pals professional pricks" another venue to spew their foolishness.
If the problem you perceive is to be resolved, the "Paul & pals professional pricks" need to move over to "alt.hvac pro-series.moderated"; the regular folks need to mercilessly "kill file" in alt.hvac the "Paul & pals professional pricks"; and regular folks need to use alt.hvac for any and all homewowner questions.
