Conventions are the rules of behaviour, spelling etc that we all keep to. They free us from annoyance and bewilderment so that we can get on with the important things in our lives. All civilised societies have them, and they help those societies to remain civilised.
I don't recall anyone inviting you to post messages to this board, Orphia. But if you choose to do so, it is reasonable to expect you to keep to the board's conventions. You can't just walk into a room full of strangers and scream for attention, which is what you have done.
