Blogger doesn't provide any solution to edit comments. Here's an easy way to edit comments posted on your own blog: Right click on a delete comment link ( ) and copy-paste the shortcut in the form below. This Blogger hack doesn't work anymore.
An easy way to add a previous post page link in the top of your blog (classic template): « Home | Previous Post Title » Just paste the code below before the <Blogger> tag. <ItemPage> <p style="text-align:center"> « <a href="<$BlogURL$>">Home</a> <span><BloggerPreviousItems> | <a href="<$BlogItemPermalinkURL$>"><$BlogPreviousItemTitle$></a> »</span><span style="display:none"></BloggerPreviousItems></span> </p> </ItemPage>
