Grunger, I felt very sorry for you when i worked out the stuff about your sports terminology being tweaked, changed, politically correctisised (if they can introduce new words, then so can I!). I think you shoukd stick to your guns and never use that daft word from today's crossword. I have no problem with many of the old (and to only a few people, obsolete) words - draftsman, chessmen etc. I am not so keen on the ones that have fallen by the wayside - poetess, conductress, the awful bishopess that was in a recnet crossword) and I am glad those have gone.
PS I don't think the '-er' ending is necessarily masculine. Most of the time, surely, it's just an agent noun? A dancer is someone who dances, a walker is someone who walks, a singer is someone who sings. Those are far more prevalent than 'mister' and 'cricketer'.
