I have not expressed an opinion to this point, but I feel that as much as a photo contest should be inclusive, it must also be specific. In as much as it may, by being specific, exclude some participation, that is the nature of photo competitions.
I have sat some out and not complained, nor even made a comment except to say I would be sitting it out. In one case last summer, Jerome kindly saw my circumstances and offered me one of his un-built crane kits. It took some scrambling, but I managed to erect it in one afternoon and present an image. But for Jerome's kindness, I would have been a non-participant.
I think there is nothing wrong with specificity, even if it excludes all those who model almost exclusively steam as I do. I also feel the subject, F-units, to be a good one that is very largely inclusive. In context, that means early diesels, and I have no problem with that. Turns out I can participate, but even if I were not so, there can be no guarantees that all contests will be playable by all registered members of this series of forums.
So far, to our contest host, you have F-units entered. It might be a prudent time, as a gentle suggestion, to nip this in the bud while they are all compliant (at first glance) and state that, once and for all, the theme will be specfic, and solely on, F-unit series of early diesels.
I offer that with full respect and deference.
