My old bookmarks for two obsolete/read-only forums are leading to
errors:

   Alpha servers:
https://community.hpe.com/t5/Alpha-Servers/bd-p/bsc-435

   Tru64:
https://community.hpe.com/t5/Operating-System-Tru64-Unix/bd-p/itrc-281

   Error message:

Access Denied
You do not have sufficient privileges for this resource or its parent to perform this action.
Click your browser's Back button to continue.

Or else some kind of site error, which I can't reproduce at the moment.

   If these forums have been intentionally eliminated (rather than only
put into an archive mode), then a more helpful error message would seem
appropriate. If this is an unexpected error, then fixing the problem(s)
would be nice.
