I also apologise to the people I scolded for truncated thread names, now that I realise that the fault was not theirs. I guess none of the six people were bad, not all bad anyhow.
If instructions are to be added, I think they should appear after one clicks on 'create a new thread' rather than on the main forum page. I can see both sides of that issue, but there's a lot on the main page already, and also I hope newcomers browse existing messages before they get ideas about making their own. The instructions should be fairly concise, but it might be worth including specific wording for 'Lyr request' 'Lyr added', whatever; if most of us use the same wordings, I expect it will ease the work of the DT compilers
See the 5th and 16 Feb (Doppelganger/Philippa/Pete M) entries at a threadiquette thread for discussion of another suggestion re wording of message
Also - if Mudcat Help is working - clickable links to information about HTML and ABC/Midi could be added to the heading at that site.
