Hyperfried, time for me doesn't matter too much.
Some of the events I do for my clan that they respond very well to are things like drop parties, wilderness games, and best yet, scavenger hunts (very fun!).
I am currently working on creating a scavenger hunt for which the main goal is to allow new members to become acquainted with my site, my forum, chat, and my shout box. The final product should be quite impressive

. Anyhow though, good scavenger hunts combine clever riddles for the identies of the needed items, bizzare yet common items in runescape, and a riddle for a secret location of the riddle moderator. I also like giving second, third, and fourth place prizes for runners up.
This is just how I do my scavenger hunts...truthfully I am not sure how SeeD does its...never attended one. Just some suggestions.
