NickorWan, when I check-solve or vet a puzzle, my input is detailed and honest, though I try to encourage rather than hurt a new, inexperienced setter. I agree about the usefulness of ALL the comments and know that a lot of friends anxiously or eagerly await the reaction here and elsewhere. However, as I have implied above and I think Radix meant the same, there is a rather different angle involved in starting a thread.
My feeling, too, that I have expressed on these threads before, is that there must be kinder ways of expressing one's disappointment than words like 'underwhelmed'. That is a real downer for a setter who has perhaps put several months into his creation then waited two years to see it in print.
