There are dozens of FB groups out there for inspectors. IB is just one of many, many. many groups.
Some let in vendors, and it becomes sales pitches, drama and association wars.
Some are full of new inspectors who want someone to hold their hand rather than go take an actual class.
Some are just inspectors who are down to ask and answer questions for when you come across items in a home you are not used to seeing.
I have been in many groups and left most of them.
