Creating a subscription
To subscribe to something, just click the subscribe link! You'll then receive notifications for that item everytime it is added to. Exactly what type of additions trigger a notification will depend on your preferences and any blocks you have set (see below).
Reading subscriptions
When you are logged in, you will see the number of new subscriptions in red at the top left of the page. Clicking the link will take you to the New Items page (alternatively, you can go to My Geek > Subscriptions in the menu).
Next to the number of new subscriptions is the 'Next New Subscribed Item' link: 
. If you are reading a subscription, this link is also at the top and bottom right of the page.
New Items page
The New Items page shows your unread subscriptions, grouped by category (Forums, GeekLists, Images, etc). Within each section, subscriptions are not grouped any further, and are shown in ascending date order - i.e. oldest first. You can switch them to show most recent first, but this setting is temporary. On this page, you can mark individual threads as read.
New Items by Subscription page
The New Items by Subscription page shows your unread subscriptions grouped by category and sub-category. Sub-categories groups can be expanded and collapsed within the main category, and the entire sub-category marked as read.
Next New Item
Takes you to the next subscribed item.
