Have just created a WWB form rather to replace a third party form, all looks good except when the form is SUBMITTED, it opens my email programme instead of emailing the form to me. Any pointers?

when the form is SUBMITTED, it opens my email programme

This is due to you having set the form to use mailto..
Please see the following including Related Tutorials at bottom.
Why shouldn't I use 'mailto' in the form action?

That solved it, thankyou. One addition though, The email reply is SOOOOO boring in presentation, is there a way to improve appearance? i.e Formatting Text size, colour, spacing etc? within wwb?

Maybe this will be helpful?
