what's inside
Writeups and walkthroughs
Markdown with terminal output blocks and syntax highlighting. Group posts into series. Writeups tied to a live event stay hidden until it ends.
Skill dossier
A profile that shows what you can do: a skill radar, badges, rank, and everything you've published.
Study teams
Form a team with people at your level or ahead of it. Captains, co-captains and reserves; open, invite-only or closed.
Practice events
A board of upcoming CTFs. Register your team and get a private war room to claim challenges, track solves and share notes.
Invite codes
Bring people in with codes that expire, cap their uses and can be revoked. Every redemption is logged.
Terminal palette
Press Ctrl+K to navigate with cd, ls, search and join. A few commands aren't documented. Look around.
