There an online petition on the Parliament site to revoke Article 50, for anyone who wishes to sign. Be warned, it keeps crashing from traffic overload, so it might take a bit of persistence.

You may see an apology-sorry-we're-fixing-it page. And if you get "Bad Gateway" it means they're really overloaded. I've had both, but my vote finally got through.

Keep trying. Stay or leave, we have got do everything in our power to avoid a no-deal crashout.
