Hm.  I've said this several times before, but once more...

_Anyone_ can create and edit pages on Emacs Wiki.

And the home page tells you this and how to do it.

https://www.emacswiki.org/emacs/SiteMap

See the "How to use this site" links on that page.
In particular, "How To Edit":

https://www.emacswiki.org/emacs/HowToEdit,

which has a link to page "Create New Pages":

https://www.emacswiki.org/emacs/CreateNewPages

Try it!  Create a page.  If you don't want it to
stay up, then delete it:

https://www.emacswiki.org/emacs/DeletedPage


And there's a "Sand Box" page, where you can try
out how to write/edit different things, to get
the appearance you want.

No need for anyone to email the wiki maintainer
and ask him for anything.  About the only thing
I email him for is if I think there's some kind
of problem with the site, e.g., the server needs
to be rebooted.
