Overe here a tip on how you can add 'Social Bookmark Tools' on your FreeDrupal website.

First you need to get the code with which it's possible to add bookmark tools. Register at www.addthis.com or www.adtoany.com and get your code.

Then go to your FreeDrupal site and login as administrator and go to "Administer". Select Blocks and click on "Add block" at the top of the page. Enter a block-title and put the Social Bookmark code in the Block body. Be aware of the fact you're entering code so select Full HTML in the Input format field. Save the block.

Now you have to enable your block, select the region (place where the block should go). If you would like to add the social bookmarkt on every article you'll need to select "content" in the Region-field. Don't forget to save the block-page to enable your new block.
