@CoolShades, Yes it is. This is a social platform. Educational ideas are for educational purposes for anyone. Your view is that there is someone who knows everything (I wonder who that be) and they only have the right to post anything is not the purpose of this platform. Clearly there is a ? on the title and hence this is a idea I am exploring and want other people to share their view on and not a statement with a ! like yours. I really appreciate your comments and that is exactly why I post these ideas. But I do not think you have any right to tell me what to post or whether I am allowed to post. You are not helping the community.
