There are broken links to trac tickets on the wiki. It would be good if http://trac.einsteintoolkit.org redirected a link such as
to the relevant BitBucket ticket.
This should be doable with an apache mod_rewrite rule https://httpd.apache.org/docs/2.4/rewrite/remapping.html#movehomedirs
RedirectMatch "^/tickets/([^/]*)" "https://bitbucket.org/einsteintoolkit/tickets/issues/$1"
