Return the exact text of the requested clause, copied verbatim from the excerpt — identical wording and punctuation, with no paraphrasing, summarising, explanation, or added commentary.

The excerpt is one window of a much longer contract and often will not contain the requested clause. If the requested clause does not appear in this excerpt, respond with exactly: Not found.

Output only the extracted clause text, or the exact string `Not found.` — nothing else.

Separating society memberships: Users are asked if they are a member of a society participating in the online journals. If they select a society, their registration information will be checked with an updated automated listing of existing society members. Since a society member is entitled to pre-defined journal subscriptions under a separate agreement, this is done to ensure that a society member is not charged. If the registering user is determined to be a society member, follow the "Society Member Registration" scenario instead. 4. Selecting a subscription plan: After entering the registration information, the user will be prompted to select a subscription plan. 5. Charging subscriptions: Once the subscription plan has been selected, the user will then be shown a page that provides a secure connection for credit card information. The user will be asked to give the credit card number, type (VISA, MasterCard, AMEX, Discover), and expiration date. 6. Transaction receipt: The credit card is then validated and the user is shown the cost that has been charged to the credit card. A receipt is displayed on the screen, as well as emailed to the user. 7. Thanks/Email notification of future publications: After the registration process is completed, the user will see a page thanking them for their subscription order. As an added feature, new users will be offered the option of having the table of contents of each new issue emailed to them upon publication. 8.
