Well, if I may make a suggestion, I feel like @entr0py would be someone who, if anyone, deserves one. He seems to be both very supportive and incredibly knowledgeable.
For what it’s worth, I feel like the current process is sufficient, simply because, at least at this point in time, the Whonix-Forum isn’t suffering under massive spam or a lot of legally problematic posts, both because of its size and the fact that for the most part, Discourse seems to filter those out pretty efficiently anyways. That’s why, at least I personally don’t feel like giving more users admin rights is that big of a priority, other than honoring those who go above and beyond in supporting the forum.
Have a nice day,
