Be an upstanding member of the community, highly respectable, offer great feedback, help new people, be active. This being said there are many people who fit the above qualifications (not reginaId) who aren't. Also the vast majority of adjudicators hark back to the olden times (before the majority of keys were given out). Emissaries and adjudicators are just a sign saying "I'm probably helpful in some way or form." You can become one, as Spunkify has (a few others, not sure who). I wouldn't worry about it though, my e-peen is still larger than theirs.
