Never mind I should wear my glasses more often.

I think if you click on your name at the top left, where is says logged in as: It will bring you to the page and right under the part you want to edit it says edit your signature and edit your about me page. ( in the my content section)

Thanks so much :-) I can't believe it was right in front of my face. Whoops. All fixed now however. Thankyou.
