Task quality was fine, but mislabeling of the task categories was frustrating. Marking a Crypto/Stegano/Forensics task as RE or a PPC/Crypto as Stegano causes a lot of confusion. Wrong people start working on the task, with wrong approach, looking at totally wrong things.
Hi Pharisaeus, thank you for your feed back. We will modify for next events the way we label task in order to avoid this problem.
