These really look terrible on mobile.
Frustratingly none of them use common templates.
I'd like to suggest we replace these pages with a warning saying that they are not formatted for mobile with a link to the desktop version.
I'd like to replace the body output of this page with "Portals are best viewed on the desktop version of the site. Button:View on desktop
The link would apply useformat=desktop
(Every time I see a portal rendered in the mobile view part of me dies)
