for posting this again - -
Here's a site (I have no connection or vested interest) that offers both free and paid listings for dances, lessons, and classes for the whole of the UK.
on a self-entry basis. A paid ad costs £10 + VAT for a year so that's coppers a week - - but of course you can try a freebie ad first - try before you buy I suppose.
Link should work, but you may have to cut and paste into your browser - - -
