"<Made by name>" tag in description of crafted itemFollow

I am just wondering what crafted items will have the "<Made by name>" tag in its description? Will the description be gone if the item is mailed, traded or sold at the AH? Also, is the tag visible only by the creator of the item or by all players?

I like the fact that it says who created it.. it is like free advertising, I know only the owner/wearer of the piece will see it, but they will tell ppl where/who they got it from.

For example, I can make the imperial plate set on my server, and have got tons of whispers to make it, after a few sold on the AH. It was nice to get some gold back while lvl up my BSing, people dont mind paying up to 85 for the whole set, which is more then what I would get from the Thorium ore/bars on my server.

Regards,

p.s as stated above yes the name will always be there
