AddThis is a very popular sharing tool so hopefully many of you are familiar with it's interface.

On any thread on S3F, you can hover the share button to bring up the AddThis menu.

I added some of the most relevant and most used social bookmarking sites that many members here use or are familar with. But if there are others that you use that are not listed, just click "More..." AddThis has virtually every service you think of, you can even use it to bookmark it to your internet browser.

If you click a service, like Facebook, you will either need to be logged in or log in so you can share this thread.

Most services will require you to enter a description or a title, but once you fill out whatever the service requires, the thread will be shared as easy as that.
