Obviously I seem to lack every single point Slyfox has made, so thanks for the insight.
One query I have though is the avatar point. I have tried many a times to pick an avatar, but when I click on the link to do this, where each picture should be is a red x in the top corner meaning I can't see what the avatar is. Is there any way to sort this?
Apart from that, thanks for the time to show us how to improve. I will try working on it.
