This info was passed on to me from another team I am on:
"This information came to me from another member
Through another blog I just learned of a new feature on SparkPeople that automatically added a "Share Bar" to our blog entries. I do not like this feature.
If you'll notice your own blog now there is a "Share" bar at the top of the blog. That means if someone likes your blog entry they can "share" on their Facebook wall!! Who wants his/her blog about losing weight to show up on someone else s' facebook wall?
To delete this "Share bar" feature from your blog do this:
Go to your SparkPage.
Click to Edit the page.
On the top Un-check "Show share bar on my blog posts".
Save your changes. "
Personally,I do not want anything I write to show up on someones facebook wall. Just passing along the info in case anyone wants it.
Have a great night!
