why you are moving sub pages (to stand alone pages)
(btw: one day before (sunday 2019-03-17) i was directly on the other side of the wall the fedora flag was pinned (at the Chemnitzer Linuxtage/2019).
nice to see activities on the wiki
The whole subpage thing is a left-over from the migration from moinmoin to mediawiki. It's still possible to use it but nowadays most pages are miss-placed and already belong to a category.
no. i was doing it that (sub page) way. i thought that is the best way. (are there other guidelines for that?)
now you created a (circle) problem (by accident).
Category:Flock 2017 → Category:Flock/2017 → Category:Flock 2017 Category:Flock/2017 → Category:Flock 2017 → Category:Flock/2017
you can see this at Special:DoubleRedirects.
would you like to roll back all your "moinmoin" changes?
The Page naming section of the structure docs says not use nesting anymore. Those rules are not enforced but a category "Flock/2019" looks wired.
Thanks for the hint about the redirect issue.
