One idea mentioned in-game by some lad (forget his name) was to add the option of displaying yourself as 'looking to craft' (much like the 'seeking group' function).
e.g. A player looking for a Tailor can open the '/who' windowandtick the Tailor, Outfitter, and Looking to craft boxes. It would now display all the Tailors and Outfitters who are currently looking for work, or craft.
