I'm on the "committee" for the homesite contest but truthfully I'm just there as an Arachne representative and it's Heraklia's ballgame. Last I heard she was thinking of having it be world oriented in that winners would be appointed to each world (one or three I don't recall) then one overall sitewide one from those choices. So it sounds like not only an opportunity to shine in your particular world, but to have your world shine in all of AW perhaps, through some clever decorating contestant anyway.

Not quite a theme, but setting themes can get rather sticky. I'll tell you one thing though, as a past homesite contest judge here in Arachne, it's the homes decorating on a theme (ie; all the rooms reflect a continuous or similar style) that got chosen every time!
