About the Recent Comments widget

Download your template before installing. I noticed a problem afterward where page elements were immovable on the Edit Layout page. If this happens to you (and you have downloaded your template) you can either edit the widget and copy the code, upload your template again then Add a Page Element > HTML/Java and paste the code there.

Luckily I had just revamped my blog and had already downloaded my template.

A much easier solution would be to use the site this way: After entering your blog address hit the "apply" button then hit the "add widget to my blog" button. This will bring you to the Add Page Element page. Don't "add widget", instead use the "Edit Content:" link and copy the code there and add it manually to your blog.

Back-up your template regularly. Especially if you have a custom template.
