The Individual Subscriptions section allows you to see all individual subscribers, edit their accounts, and create new ones.
To create a new individual subscription, select the link. If the user already has an account with the journal, you can sign them up here using their link.
Once that is selected, fill in the resulting form.
If the new subscriber does not already have an account, you can create one for them by selecting the link at the bottom of the screen. You then need to fill in the resulting form.
After filling in the form, you will then need to them from the list of existing users and fill in their subscription details (as in the previous section).
