Let's say I'm crafting a coyote trinket and I've just produced a masterful coyote trinket. The game would echo something like:
Then I could type:(You've just produced a masterwork item! You may submit a customized description for approval for this piece with the DESCRIBE command.)
Or whatever. I'm not good at writing the best descriptions. The game would then echo:>describe Calm, stoic eyes gaze out from the remarkably lifelike coyote image carved into this trinket.
This would notify all GMs online that someone just sent in a customized description. The request would be attached to that item so GMs would know if someone tried to pull a fast one and get the description put on something they didn't make.(Your custom description has been submitted and entered in the queue for GM approval. You will be notified upon your next login if the design has been approved or rejected, or with an altered suggestion based on the one you sent. Please be patient, our GMs are very busy!)
GMs could then do something like CUSTOM QUEUE or whatever, to show a list of customization requests that are waiting in the queue, and approve, reject, or suggest alternatives. If approved it would automatically update the item's description.
Anyway I don't know how the MUD is set up since it's a custom codebase, but this is just an example of how a system like this might work. I think it would really make crafters happy.
