For development and testing you don’t need the production environment. You could use a demo installation instead, and after thorough testing an admin could install the AWM app as .xar import in production: https://www.xwiki.org/xwiki/bin/view/Download/
Using LiveData tables than only requires write permissions.
That would be my preferred approach.
Things like that are possible, using scripting, for example:
{{velocity}}
$datetool.format("dd.MM.yyyy, HH:mm", $doc.date)
{{/velocity}}
Or [Solved] Display a list of pages with a specific tag …
You can do plenty of nice things with scripting in xwiki. However, velocity requires script rights, both initially and for every subsequent edit of the page containing the script. Other script languages requires programming rights.
With display or include you would have to do this by hand after every meeting - possible but much work.
