What browser do you use? I can tell you how to turn spellcheck on in firefox if that's any good?
Actually for anyone else reading and using firefox, click on the spanner in the top right corner of the window, just under the x. Choose options. Then on the left side choose 'under the bonnet'. Next to web content click 'languages and spellchecker settings'. Make sure English (United Kingdom) is highlighted and then under that box it says enable spellchecker, click so there is a tick here. Now whenever you type anywhere online it will spell check it for you as you type.
