Would it be possible to provide a mobile version of this forum?

Currently, the site appears overly zoomed out when viewing on a mobile browser.

I know that the site suggests that users download tapatalk, but I (and maybe others) would prefer not to have to install a separate app just for viewing this forum.

It seems that the phpBB package does provide responsive layouts that automatically adjust for mobile vs desktop displays.

For example see this forum, which automatically displays nicely on mobile browsers.
