Yes we know it is a little unusual and yet we have come to love/tolerate it.

It doesn't like British spellings, and it has a fairly limited number of words in its memory. We have called it Enigma/Ænigma and there are plenty of posts on the subject, if you care to use the search facility. (Enter all forums, all dates - Enigma or Aenigma).

A useful alternative, used by some of us, is to install Atomica (formerly Gurunet). There is a free download at http://www.atomica.com/ this will enable you to check any word using the alt key and the mouse.

There are also a lot of useful on-line dictionaries discussed in:

If you feel the need the correct someone else's spelling then some of us are not so keen about being corrected in front of the whole world, particularly when we are unable to usefully spell-check out own contributions. You may like to send a private e-mail if you think your comments are constructive or helpful in any way, otherwise you can decide whether you wish to say anything or not. We come from all walks of life, we span a wide range of ages and several people do not have English as their first language - they are usually the ones with the perfect spelling and grammar
