In the scrolling threads of the Forum I feel it’s good to make items relatively brief, highlighting things. And maybe, to post a link to a separate document if there’s a fairly long text to share? I think HackMD is pretty good for this - a free online Markdown editor which publishes web pages.
An example Community development - A Community circle @ meet.coop? - HedgeDoc Don’t be confused by ‘Hedgedoc’ - it’s a rebranding of HackMD, same tool.
