yw yeh the breeding 101 isn't like that, I mean you might see some judgmental comments about a breeder with a known bad history, but even then the admin are quick to put a stop to it.
Breeders that have made mistakes in the past whether on purpose or not are judged pretty harshly by the community as a whole, it's practically unavoidable for them to be brought up without their history being brought up to. The community forgets and rarely forgives anything. Most of the time it's simply word of mouth by people who have never even had dealings with the breeder. However, in this group if that breeder wants to and are there to learn and improve their breeding program and practices they are welcome.
There are a hand full of no drama glider groups on facebook that focus on all levels of glider education whether you're a new glider owner or not.

These are two that I really like the mentor group isn't that active but it's a good resource non the less. If your new to breeding a breeding mentor might be beneficial to you to answer questions one on one if your interested I can give you a couple recommendations
I know you said you have a mentor but if they aren't versed in breeding a experienced breeder mentor might be a good option to add to your education
