Another fun little addition for tradeskills and crafters straight from the Beta realms is the ability to peruse the recipes that someone else knows. It works very simply, too. The crafter links his tradeskill like it were an item. You click on that link and a regular tradeskill window pops open, minus the option to craft, create or enchant what you're looking at. You can see all of their recipes and the materials required for them.
This seems like it's going to be especially useful for the tradeskills that have a large variety of things that people need. Jewelcrafting, Enchanting, et cetera. It would be much easier to link a guildmate the list of what I can do rather than look up everything they need myself. "Can you do Savagery? Vitality? Spell damage to bracers? MP5 to chest? Strength to gloves?" Maybe! Here, check and see!
Linking your recipe book over the Trade channel should help sell enchants and inscriptions as well, hopefully replacing the endless spam of three paragraph advertisement macros. Okay, so maybe those macros will never go away, but we can hope can't we? By the way, you can click on the image to the right to make it bigger, in case you can't see it very well as it is.
