Just out of curiosity what do emissaries of the league and adjudicators do? what qualifies peopel for those positions and how do you become one?

Adjudicators are adjudicators because they played the beta before July
Emissaries are emissaries because they used to hold Noob Q&A sessions a lot in vent until they would be allowed to become emissaries

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.

oh, now how does one go from being a junior member to a member to a senior member?

Postcount, not sure but I think member is 50+ posts, senior 150+ posts.

Hmm what do we do you ask?

We mostly just schedule adjudicator sleep-overs, and stay up all night talking about our hopes and dreams and how awesome Teemo is.

In case you were unaware, i'm kidding
