Yes, this is what I would like to know, too. I'm not sure about the LV forum but I've had a couple people report a new member helping out in the Bal AT thread. The problem for me, as a moderator, is that the person's advice is spot on. They haven't made any mistakes, so until I see that a person is misguided, I can't step in. There is no reason to, we have no requirements that a new member can't help in AT if they are familiar with a brand enough to do so. However, we are told by our familiar Authenticators that someone is making mistakes and doesn't know what they're doing, we will absolutely step in. At least I will, and I know my fellow mods would too. But if it's just a matter of being a newbie..

I don't know what to say.
If you see a new member making mistakes, by all means REPORT!! And feel free to respectfully let others in the thread know a mistake has been name. If you are alerting a moderator about mistakes and are not getting a response, please feel free to PM me as well and I will help.
