Currently meetable supports tag browsing pages like: https://events.indieweb.org/tag/hwc
However if you trim the last segment, you get a 404: https://events.indieweb.org/tag/ or https://events.indieweb.org/tag
Meetable should instead redirect those to: https://events.indieweb.org/tags
Additionally, Meetable should consider redirecting https://events.indieweb.org/tags/ with the trailing slash to https://events.indieweb.org/tags without the trailing slash instead of serving duplicate content at those two URLs.
