The previous article covered adding a slideshow, we will now show you how to add a Guestbook / Comment block in Concrete 5. This allows visitors to leave messages on your site, or comment on posts from other visitors.

Guestbooks can be useful for providing a place for people to interact with your site, which can make your site more fun and entertaining.

How to Add a Guestbook:

1. Login to your Concrete5 Dashboard.
2. Navigate to the page you want to add the Guestbook block to, by clicking it in the menu bar.
3. Click the Edit button on the top left. This will allow you to make changes to this page.
4. Select the area you want to add the block to, in my tests I want it on the top of the main content page, so I selected Add to Main.
5. Choose +Add block from the menu. This will bring up the Add Block menu.
6. Select Guestbook / Comments from the list, which will bring up the Add Guestbook / Comments menu.
