Thanks all for the warm responses. The welcome message as updated by @etadobson reflects most of what I had hoped for. Concise and inviting to read more before posting.
A few things make me hesitant to tick its
-The no-image-on-first-post limit (which gave me big frustrations on my first post)
-A ‘missing link’ in the text on the text original image file to a page that describes what we expect to be a useful sample (image) file.
-The use of the
name tag in the html, so one can link to /18727#TipsForFirstPosting.
In support of @imagejan and @bcimini, to sort of convince @etadobson, and on my first point of hesitation, maybe the reward system of the forum software could reward new posters who have read the welcome instructions AND followed the suggested missing link above on what is ment with an original image, by allowing them to post an image in their first question. Alternatively, and this connects to my second point, maybe the system could allow to post only ‘best practices’ files on the first post. I doubt if bots are smart enough to in their first attempt both tag ImageJ/FIJI AND post a tiff format image…
The missing linked page would then describe the best practices of sample files for the application that was tagged. For example, to counter the often upcoming discussion on poor jpgs when using ImageJ/FIJI while tiffs are best practice, maybe workflow files in other apps, the use of the preformatted text tool on a macro tag. But I digress.
Pointing first time posters to the Welcome message, to the tips specifically, would alleviate my third hesitation.
Thanks again, all, for your opinions and help.
