Thank you, Amadan (and others here), for your thoughtful response.
Amadan: re: your second paragraph... presumably you (or a fellow iSpot user) is keen for a less experienced user (like me) to learn from your corrected ID. And therefore, presumably, so long as the less experienced user has checked out your suggestion and found it to match, it should be a good outcome (shouldn't it?) if an updated ID along those lines is then added?
But perhaps I am missing something here... I'm sure those of us who are less experienced on the site are learning so much from those with more knowledge, and that it is this process in part that is (a) making the IDs more accurate in the end and (b) helping us to learn so that we in due course can begin to have the skills to help others in the same way. But I may have misunderstood you? I know for myself that I am extremely grateful to all who give me a helping hand - so thank you all.
