Users can subscribe to receiving notifications about new blog comments in a blog post. ## Enabling subscriptions in a blog You can enable users to subscribe to blog comments by checking the **Allow subscription to comments** box on the **Form** tab of the corresponding blog document. ## Enabling double opt-in for blog subscriptions To make users confirm that the e-mail address they're subscribing with really exists and belongs to them, you can enable the double opt‑in functionality. With double opt‑in enabled, subscribers will be sent an e-mail with a confirmation link. They will have to click the link to create their subscription. **To enable double opt‑in globally for all blogs** 1. Open the **Settings** application. 2. Navigate to **Content** **-> Blogs**. 3. Turn on the **Enable double opt-in for blog post comments** setting. 4.

You can insert the confirmation link into the template using the _{%SubscriptionLink%}_ macro. ## Allowing users to manage their subscriptions on the Live site You can allow users to manage their own blog post comment subscriptions by placing the **My account** web part on a page. ### **To place the My account web part** 1.
