Guild Ranks, what comes with them and how to get promoted

Sober - Starting rank. Can post in guild chat only.
Double Vision - Alts rank
Tipsy - The rank you obtain by registering here. New abilities: Access to guild bank (1 withdrawal per day).
Drunk - First of the ranks obtained through longterm assistance to the guild. New abilities: Access to officer channel, invite to guild access.
Wasted - True officer rank in the guild. New abilities: promotion access, demoting access, remove member, set guild message of the day, edit public and officer notes.
Space Cadet - My rank. Head huncho .

Now if you want to make your way up in the guild beyond tipsy then you need to act selflessly, assisting guild members in need (not through running them through a solo run of an instance though), setting up guild runs, contributing to the guild vault etc. Promotion is never earned from a single act, but of many over long periods of time.
