The other change is a bit more complicated and is more to do with
improving maintenance rather than formatting.
I've created (well all right - copied from another wiki) a new
template -
http://wiki.crisiscommons.org/wiki/Template:Delete_page
Most users can't delete articles. If you've created an article that
you no longer have a need for, perhaps because you've merged it with
another one, or it has just passed its sell-by date, put the markup
{{delete page}} anywhere on the page, and an administrator will be
along at some point to dispose of it for you. If you like, clear the
rest of the page contents and add a small justification for deletion,
but you don't have to.
Putting this markup on a page will add it to
http://wiki.crisiscommons.org/wiki/Category:Articles_to_be_deleted
Which brings me nicely to - please have a look at articles/pages that
I've already marked for deletion, and if you think that my judgement
is wrong, please feel free to rollback the changes and/or tell me.
Many thanks!
