Decided to try JS-Kit Comments first and got it up and running in less than 10mins! ;) I literally had to add only one line of code in some of the nanoblogger templates.

For those wanting to try JS-Kit to add comments in nanoblogger you just add the line

<font size="1">&lt;br/&gt;&lt;div class=&quot;js-kit-comments&quot; path=&quot;/comments/$NB_EntryID&quot;&gt;&lt;/div&gt;</font>&nbsp;

in entry.htm and permalink_entry.htm templates after the Permalink or the Categories link and then add the line

<font size="1">&lt;script src=&quot;http://js-kit.com/comments.js&quot;&gt;&lt;/script&gt;</font>

anywhere in the body section of main_index.htm, month_archive.htm, permalink.htm and day_archive.htm and you're good to go.

Follow the instructions in the JS-Kit Comments website on how to manage the comments on your blog.

Next I need to figure out if I can actually make a backup of the comments using their RSS functionality. Cheers!
