Send invites from Settings → Members → Invite. Each invite is a single-use email link; the invitee creates their account during acceptance and lands in your org automatically.
What the invitee sees
After accepting, the invitee runs through a short personal-setup flow — role (CFO, CHRO, CRO, etc.), intelligence interests, disposition (optimist, pessimist, balanced). This data tunes the Numen personalization row across every module so each person sees a tailored read.
Revoking
Pending invites can be revoked from Settings → Members until accepted. After acceptance, the user becomes a member; remove them via the same screen.
A note on role at invite time
You pick the invitee's role when sending the invite. The role can be changed after they accept.
