To secure the system against such persons, each subscriber must either pay a high set-up charge or obtain a code from another subscriber.

The system is currently growing primarily by "word of mouth". The subscription offer (below) includes a "promotion code" field. If you know the current promotion code, enter it, and the entire payment for today will be waived. Subscribing today at full price will essentially be a donation, since the system does not yet offer any content.
