You edited your earlier post.
Requiring certain credentials in order to REGISTER obviously would not work. Those registering on this forum are generally here to ask a legal question because they do not know the legal answer.
Those RESPONDING to the questions should have legal knowledge so they can provide accurate legal answers - or they should have research skills or experience enough to provide accurate legal answers.
Inaccurate answers help no one.
You came here with a legal question because you didn't/don't know the law. I have not yet seen that you have skills to research laws. Until you know more, it would be better for the posters who come here if you refrained from posting until you have something of value to add.
