With apologies 

Hello, MusicTeacherClub. I appreciate your efforts and thank you for contributing to our encyclopedia.

I'm sorry to inform you that you're contravening Wikipedia principles, namely Wikipedia is not a publisher of original research and accounts must not be shared. Unfortunately, this may lead to your being blocked or your contributions being removed.

Wikipedia tries to aggregate information that reliable sources have previously published; we do not publish original research ourselves. If we allowed that kind of thing, we would be putting two fundamental tenets—WP:Verifiability and WP:Neutral point of view—in jeopardy. I advise you to save copies of your articles to your computers, particularly Learning-Disadvantage Gap, as it may be deleted from Wikipedia soon.

A less fundamental problem is that shared accounts are not allowed. I don't really know why (I'm pretty new here); maybe we've had problem editors hide under group accounts in the past. Whatever the reason, the fact that you are a group of people sharing one account is grounds for blocking.

I'm sorry to bear bad news. I wish you good luck in finding a publisher. 

Sincerely,
