If the comps are to continue, such parameters need to be spelled out clearly at the time the comp is announced, before entries are submitted. In the interests of fairness, people need to know ahead of time exactly what the ground rules are, otherwise it isn't fair to anyone.
IMO, if a prize is offered it should be awarded even if only one person enters. Even if no prizes are offered, a winner should be chosen and announced even if only one person enters. A comp should not be left to die a slow death no matter how few people enter.
maybe competitions on photo-shopping or creativity in how the photo is taken? Its been done in a few forums ive been on and it worked well im sure it would be possible to change the colours of snails shells and stuff or to change the background and put them in silly place or something? just a suggestion
totally agree with coyote, competitions and contests should be well thought out and announced and detailed. I myself probably won;t be part of any, as I usually am not that type of person, but you never know.....it is hard to make contest not bias, doing things totally anonymous would help that, but often that doesn't work either as people tend to leave tells, not to mention a lot of us recognize each others snails from previous pictures, either the friends themselves ro the setups, or etc. it really does take a effort to be fair sometimes, and many lack the ability to actually be non partial....and many things are subjective anyways. good luck with it though......it sounds like lots of people have fun with such things, and it would probably bring in more people if it was advertised on the various facebook pages/etc to the forum here and to the hobby.
