Hi Margy -
They will if someone wants to post them there and clicks the link. I understand your concerns, but keep in mind that they can already do that by copying and pasting a link to your posts (or anyone's, for that matter).
This just makes it easier.

So if I am understanding this , my answers will go up on facebook, my space ,and twitter whether I want hem to or not ...
Some people do like to share information they find here on their other social sites. So if they wanted to link to a MedHelp post on their Facebook page, clicking the Facebook icon would paste the MedHelp question over there on their page. The post and answers would be shared with whoever the member lets view their Facebook page - friends, family or the world.
It doesn't have to be a post or answer you made to share it - you can link to or tweet any MedHelp forum post that way.
Please note that any visitor or guest to MedHelp can also see all the forum questions and answers posted here. If you tweet it (or face? it), then that will provide a shortcut for the people following your Facebook posts or Twitter tweets.
Hope this makes sense!
