If I go to an old topic containing links to old forum posts, as the links are static they have retained the old domain; and, for me at-least, the old domain does not redirect - requiring manual link rewriting.
Example:
Link contained within:
does not redirect.
This is not a major issue for me, but it may hinder other users in navigation - I can think of two relatively simple solutions:
Automatically rewrite all links in the forum containing:‘qubes-os.discourse.group’ to ‘forum.qubes-os.org’
Maintain a redirect for qubes-os.discourse.group to forum.qubes-os.org (if this is possible?)
