i think i am able to commit the time.  there are occasions during the year when i'm on holiday for 1-4 weeks when i would not necessarily have internet access (international travel).

i would not want to use my main user account for this, though. but rather an alias, so as to not invite confusion between me the user, and me the moderator.  plus, that way i could argue with myself and it wouldn't look too weird :D

i am in sydney, australia (for the most part) and typically online in the late morning (sydney time).  on weekends, i would typically be on in the early morning (~7ish) 

cheers
