I don’t have permissions to post in the plugin dev forum, so.. I created a plugin to add the ‘addtoany’ bar to my sites (http://www.addtoany.com/), only for the 1.x series.
Downloads on my site;
https://redmine.bloodycactus.com/projects/ee1addtoany
I googled a little but didn’t find that anyone else had written a plugin for this so I knocked it out (my first, quite simple actually).
add the tag to your templates
{exp:addtoany name="{title}" url="{title_permalink}"}voila.
I’m not quite sure how one gets it listed on the EE site but anyone can download and drop it in their plugin directory.
