Guest, if you were using your brain cell (or even your brian cell, if that works for you) you might have read what I put in the thread ... the casting director was going to use actors, and my husband suggested real dancers would be better ... and that his wife (me) could possibly help. And if you read the thread you'll see that the ridicule of the request comes from people who are not, themselves, dancers.
Next time my husband thinks of a helpful way to put the right people in the way of earning some money, remind me not to put a thread on Mudcat where so many contributors to this thread clearly have nothing better to do with their time.
Just as a comparison, when an actors' forum puts out a suggestion that properly skilled actors might be able to audition for a paid role that uses their skills it tends to have a very different response.   People are normally pleased to hear of work opportunities in their specialist area ...oh, sorry, I forgot. The people who are being so unhelpful on this thread aren't the ones it was addressed to in the first place, are they?
