She is not being rude - it is common practice to tell people that they have used the board unneccesarily. And despite what you might think, the board
does get too full, and genuine queries get lost amongst the posts of people who can't be bothered looking things up for themselves.
I don't recall having seen your name around before, and you're not registered, so I would recommend that you wait until you've been here a while before you start telling long-term members like
Lala what to do.
