Just a thought...
With the arrival of the new forum, I see a lot of posters have forgotten to use code tags...
Would it be possible to add a simple text prompt (in red!) across the top of the text window...
When a new user has less than xx posts, it says... “When posting code examples, please use the </> code tags to format your text.”
This can disappear after they reach a certain skill level.
This text, and that of the "community guidelines" are currently just the stock text provided by Discourse, but it is possible to customize them.
There is also a "Greetings!" PM a new user is directed to read after signing up. This contains an interactive tutorial with a bot where they learn about using the forum and demonstrate their understanding of that information:
My mind skipped a track… this was meant to be under the New Forum thread !
Sorry, mea culpa.
It came about, because the new forum allows posters to submit very long blocks of code ‘illegally’, which aren’t contained in a scrolling code window… just makes it harder scrolling through untidy posts, especially on mobiles.
