Individuals are accepted into this matchmaking-for-first-date service (part of NewEco) only after RLLink has verified their photo+name+location by path from master user.
.
Couples are matched per three conditions:

• They are visually attracted to each other.
• They are compatible for topic-specific online text communication.
  Maybe use surveys to do preliminary screening on interest in topic (choice of poll question within meta-survey) and opinion about topic (choice of answer to topic-specific poll question).
• They agree what to do on a first date.

All three must be successful, independently, for the same two people, before a full OneDate "double match" is declared and the couple-to-be starts to negotiate scheduling a first date.
.
After that first date, they go back to online text communication, with each other and with the OneDate matchmaker, to discuss how the date went and what changes if any would be needed before a second date with each other or new first dates with other hopefully-more-compatible people.
