Right now there are two options for the users:
1. Anonymous ones, who see the classic "subscribe" option (text input field + button)
2. Logged-in users, who see only the "subscribe" button.
Logged in and subscribed users don't see anything at all, and that absence (in my actual design) is pulling the adjacent floated blocks, making a visual imbalance on the page header.
For this scenario, is it possible to have a third block, which will supply simply an "Unsubscribe" bouton or a Form where users can enter their email address and unsubscribe?
