Just as with the recent posts, by default the TwentyTen theme shows the last 5 comments to your posts on the sidebar.
This number is easy to change. Here’s how to do it:
1. Log into WordPress using an administrator account.
2. Select “Widgets” on the appearance section of the sidebar.
3. Click on the arrow to the right of the “Recent Comments” widget.
4. Now change the number of comments to reflect how many you would like to appear on the sidebar.
5. Click on “Save”.
Here again, there are plug-ins that allow more flexibility than this simple widget. Some third party comment systems also offer their own widgets and plug-ins. I shall be looking at both of these in further posts.
