There was no such option indeed. Changed now. Please test.
This discourse forum software supports “trust levels”. “level 4” is as far as I can see only manually given. Just now populated:
https://forums.whonix.org/g/trust_level_4
Added you.
Configured the forum software to allow all members of trust level 4 group to edit forum tags.
Anyone interested in triage of tickets can request access to this group.
Eligible is everyone where it’s reasonably certain that it’s a serious contributor. Such as people with significant, long term contributions such as research, code, documentation, user support.
Reason it’s not open for all accounts is that discourse does not have any easy way to show when tags where changed (only through post edit history) nor does notify about tag changes.
