We are pleased to announce the qualifying events for DEF CON CTF 2016! We've spent a great deal of time reviewing a record number of proposals, and had to make some very difficult choices. We'd like to thank everyone in the CTF community who took the time to send us proposals: even if we weren't able to accept your proposal, your contest is important to us and the larger CTF community.
