I find a lot of good sense in what Ed and Jim suggest. Mudcat was my first real experience of a web forum and I'm still learning. I did try the DT for the song which I was looking for at the time, but didn't turn it up - I think because of the old alternative spellings problem. Fortunately, a post on the forum produced answers within minutes.

At the same time I'm tempted to suggest that if everything is made too easy to find in the DT, fewer unsuspecting passers-by will be lured into the forum, never to emerge again...
