About Rixa Aperta

1. Pick a proposition on the board, or post your own. Someone takes the other side.
2. You argue in turns, each on a clock the creator set. Miss your turn past the grace period and you forfeit.
3. When the debate ends, readers score both sides and pick a winner. The result goes on both profiles, for good: every debate here is public, including the ones you lose.
4. Reading is open to anyone. Accepting, posting, scoring and reporting ask you to sign in: an email code and a handle, no real name.

• Each turn has a time limit the challenge's creator sets, from 1 to 30 minutes.
• After the limit comes a grace period of 2:30. Miss that too and you forfeit: the debate ends at once, your opponent wins, and readers do not score it.
• A creator who never opens the debate within 48 hours of it being accepted voids it: no result for either side.
• Scoring closes at 101 voters or after 72 hours, whichever comes first. A debate shows its totals, never who scored it which way.
• Scoring is open to accounts at least 24 hours old, so a result can't be bought with a sign-up made for it.
• An account can have 3 challenges open on the board at once, and post 5 in an hour.

Every debate, including the ones you lose or forfeit, and every turn as it was sent. Your handle, the date you joined and your record. Not your email address, which our database never holds. The Privacy & Terms page has the rest.

Rixa Aperta is in open beta: live, free, and still rough in places. The challenge board is the whole site: pick a side there.
