A module is currently installed that allows users (you) to be automatically notified of new information that is available at Northern Plain Athletics. You can subscribe to a certain kind of content (competitive event, conditions report, or article) or to content that is placed in a certain category (such as condition reports for cross-country skiing, upcoming duathlons, or races governed by USA Cycling).
This feature applies to users with accounts at Northern Plains Athletics.
Subscriptions can be managed at your user account (see "My Account" on the left menu) under the "Subscriptions" tab. On the "Overview" subtab, you can change the settings for the subscriptions for your account. The other subtabs allow you to add, remove, or change subscriptions to content and content types.
If you are looking at a node (a specific piece of content, such as a competitive event page or an article) and would like to subscribe to similar material, you can expand the "Subscription" menu on the page and manage which material to which you would like to be subscribed.
