Thank you, Georganna, especially for the example. Mammamaia: I think I saw the term ‘slug’ in the conditions for a writing contest. I must have seen ‘tag line’ there, too. As usual, I seem to have misunderstood. In my defence, I still find it difficult to get on the same wavelength as some Americans – even after thirteen years. We seem to be seeing ‘eye to eye’ only to find out later that one of us had a squint.
