1 way -For newest version of Blog.
Edit file SimpleBlog.php.
Find line 289 echo '<div class="clear"></div>';
Insert before it
echo '<hr />';
echo 'your social code';
But on blog update you lost this changes.
2 way Make new layout, from theme you using. Edit it and add at the bottom of the page - extra content area with your social code. Aply this layout only to a Simple Blog page and SimbleBlog Categories page.
Thank you for your reply, i found it!
You know if there is also a function available to work with a ''read more'' link after a certain amount of characters on SimpleBlog.php? On line 379 i see "Abbreviate $content if a $limit greater than zero is given", but i'm not sure is it's being used for my purpose..
