Thanks Nicola and K-j
Yes, I appreciate the possibility of abuse, but bearing in mind people post all kinds of other links to video and the such-like and also have to sign up, I am hoping there would be no additional temptation to post abusive material than there is now. I did post an audio file at beginners about a month ago with no difficulty so I am assuming that the permissions aspect is not water tight. I do realise you might need to make some alterations in that respect, and considering the amount of time I am about the place, I would be more than happy to notify a moderator if I noticed anything that is not appropriate. Personally I think this facility would simply be another feather in the cap of an already outstanding forum.
to anticipate touching what is unseen seems far more interesting than seeing what the hand can not touch
