Features

• One forum for every computing field. A single section with 298 preset tags in 27 families, from algorithms to amateur radio, cybersecurity in depth. Pick up to five tags per thread; filter by any combination.
• Open, not pre-reviewed. Posts appear at once. Illegal content is removed when reported, and every report gets a private receipt that shows the decision.
• No email needed. A name and a password are enough. Your password never leaves your browser: it is turned into keys there. A recovery key, shown once, replaces the usual "forgot my password" email.
• No addresses stored. Nothing you post is stored with your IP address. Anti-spam uses proof of work and short-lived counters instead.
• Anonymous board. For whistleblowing: no account, no name. Optionally sign your posts with a key kept only in your browser, so readers know later posts come from the same source, and give a nickname the signature covers.
• Encrypted groups. Make a group whose name, titles and messages only its members can read. The server stores sealed text only. A new member cannot read what came before them unless you share the history, and a removed member cannot read what comes after.
• Forward-secret rooms. Groups that change keys on a schedule and delete old messages and keys for everyone.
• Drop. Reach the staff in confidence, with no account: your browser seals the message for the recipients listed with their fingerprints, and a code shown once brings you back to read the replies.
• Ephemeral chat. Open a room, share its link, talk. No account, nothing stored; messages are sealed in your browsers. Whoever joins later reads only what comes after, and whoever leaves cannot follow.
• Markdown and code. Code blocks, tables and links. HTML and images stay as text.
