LOL,
When I first posted on here I was accused of being all sorts of things, an impostor, troll, etc (in fact if I recall rightly AC's first comment to me was something about stupid users like me coming back and making up stupid names to spoil the site..)
I ignored all the comments from everyone and just got on with quietly answering questions that I could and after a couple of months people started to realise that I wasn't a troll and was a genuine user.
As AC said, you have no history here, if you want people to respect you then you have to stick about, put up with a few comments and work at it until people accept you (or the school holidays are over and you're not bored anymore, whatever comes sooner)
Instead of just asking (often daft) questions all the time why not try and put some useful input back into the site and give a few answers too, regardless of your age there must be some topics that you can make a useful input to.
