A question regarding Facebook/Twitter posts.?

[Bo]

I know that you can link up your Facebook and Twitter accounts so that they post to each other.
Is there a way I can have my Facebook posts go to twitter, but not have my tweets go to facebook?
Facebook -> Twitter
Twitter X Facebook.
Some of you have said there is an option I need to change. Where is the option?

There is an update which lets you select to tweet to facebook in settings, so un check that and then select the option in facebook to status to twitter.
