Deliberately small, for the first few months.

Long-form writing platforms work or don't work based on the first hundred people who show up. We're choosing ours carefully — by invitation, through late autumn 2026, after which the gate comes down.

If a current member has sent you a code, paste it below. If you've been writing somewhere already and want in, send us a link to your work; we read everything that comes through and reply within 5 working days.
