What signup questions cannot do
Draw the line firmly, because the phrase pre-qualify tempts hosts toward a product they do not have. There is no approval gate: nobody's registration waits on your review, and a completed form is a booked seat up to the limit. If you truly need a vetted room, the honest tools are a cap set small, a password on the page, and invitations you send yourself.
Questions also cannot hold a seat, open a second session, or rescue a bad date. What they can do is make the first ten minutes of the session feel like it was written for this exact list โ which is, in the end, the only thing a signup form was ever for.
