To me it is simple. People should own up to what they do, and if they can, rectify it. Not hide behind a "but I'm so busy, there's no time to fix it afterwards." Then don't do it wrong in the first place!
- That means if somebody posts a double - delete it.
- And if the person is really so worried about getting their number of posts up, or of being visible to all others as always watching, hoping to get the award, or whatever other reason, then not delete it, but edit the pic out, and maybe even put a comment in there commending the other person.
- And, nobody really should post doubles. Easy to say, I've also done so and had to delete or edit. When you post but somebody else jumped in ahead of you, the software stops you and tells you that someone else has posted a new post in the mean time and maybe you want to review yours. However, if you immediately click <submit> again it will post, as the software doesn't check duplicates. In my opinion, for what it's worth, people who continuously ignore that message and just post are rude and inconsiderate - they either want their numbers up or to be seen (as per the above) and damn everybody else!!
As far as the highlights are concerned... also a path that we've trodden to powdered-dust in the past. It is not practical to say only this or that person or group can post. What is a highlight? Mine may differ from "yours", whoever "you" may be. Personally I sometimes find the lovely colours on the water exceptional, and would post that as a highlight, and the next person would think me totally daft! Opinions differ.
As far as Siobain's suggestion of also adding the others who posted... that's got merit, and I admit that I'm one that's not done that, never really considered it. Only problem I can see with that is that you're going to miss, and thus upset, somebody who also posted. Seen it happen...
I think, in the end, people should just be more considerate.
