[MM3-users] Where to put static files referred to from list Info page?

Hi friends. Some of my version 2.1 lists had some static files that were referenced from the list's HTML pages. I'd like to do the same for the lists now that they're ported to MM3.

My question: Is there a place I can put these files within the Mailman directory hierarchy so they can be linked from the list Info page?

I.e., under "Settings / List info / Long description" I'd like to include a <a href=...> to a file that's somewhere in a persistent location in the same directory tree as the Mailman web.

I tried putting it under mm/var/lists/listname/ (where 'listname' exists, and is where templates go. This yielded a '404.'

I confirmed I can add an href to the Long description, but don't know where in the Mailman3 directory hierarchy I can put the files.

Thanks! Greg Newby
