I've recently noticed that scrap.tf has stopped showing the "crafted by" text and craft numbers on items. I would like to suggest starting to show this information again, for two main reasons:
1) Several people like to put hats they've crafted themselves into raffles. The "crafted by" text not being shown makes this a much more arduous process. Previously, you could easily just have searched for your username when making a raffle to quickly find the correct hats. Now, you would have to check your TF2 inventory on steam to make sure that the hats you are putting in indeed are the correct ones.
2) Some people may want to browse the bots for hats crafted by certain people or hats with certain craft numbers. This is not possible at the moment, I believe.
