Recent Comments Widget For Blogger

This Recent Comments Widget for Blogger will display the most recent comments on your blog's sidebar, showing a snippet of the last comments along with the title of the post where the comment was made. The comments will be gathered in descending order with the newest comments at the top and the older ones at the bottom.

The gadget is coded in JavaScript and styled with CSS but there hasn't been added too much, so that it could fit the color scheme of your Blogger template.

Parameters to be configured:

a. Number of comments - total number of comments to display; 
b. Date on which the comment has been published - either display or hide it;
c. Posts on which a comment has been made - you can either hide the post titles or show them;
d. Number of words per comment excerpt - the first "n'' words of the comment will be listed.

To add the Recent Comment Widget to a Blogger blog is very easy.  Just follow the next steps below:
