Guild Quests

I think I've spoken before about how much more can be made of guilds, and I know some games have caught wind of this notion and now allow such activities as levelling up your guild, guild abilities, extended guild features, the design of the interior of the guild hall, and so on and so forth - and this is all great.  Still more could be done, and this is one way in how you do it:

Allow the guild leader (and optionally officers too) the ability to create guild quests (or duties?) for the lower ranks to perform.  This could well support the ongoing development of the guild.  Say the guild needs 100 units of wood in order to extend the guild hall - or gain access to a certain specific interior design.  All the guild leader need do is create the generic guild quest (available to all guild members) and then members can go off and do their part toward obtaining enough wood.  Consider this notion when applied to virtually every facet of guild development and the game could provide a robust, automated system for guild development.
