Create a 'quest' channel. This way any character can run a quest for lowbies, etc. and offer rewards. Example:

QUEST Saagkri: We're trying to re-open farmer griff's shop in the Emerald forest now that the goblins have settled down a bit. But we need some stock.

QUEST Saagkri: So, first three adventurers who have not reached the fifteenth circle in their guild to get here with ten different food items will be given a girdle of endless space filled with goodies for your travels!

I've thought about doing this IC before, but the idea of sending tells to all the newbs seen and unseen makes it less appealing.
