It's better to stray on the safe side, and not reveal effects, even if they are yours -- as, there is no way of knowing whether an effect, which is being revealed, is an effect that has been truly invented by the person revealing it.
Therefore, while I understand that you would like to share your knowledge and spread your invented magic to other members, just to be safe, do not reveal any effects, whether they are your effects or not.
