How to... Start / Stop twitter updating your Facebook status

Actually two how to guides.

You need
1) A facebook account
2) A twitter account

Firstly How do you get twitter to update your facebook profile?

Install the twitter facebook application

Give it required information to link it with your twitter account.
When set up it will show your tweets and the twitering from who you may be following.

Above this box it should have a " Allow Twitter to Update Your Facebook Status " balloon when clicking this will let twitter update your facebook profile.
I doesn't work the other way round, so updating your facebook status does not invoke a tweet.

Secondly How to stop a tweet updating your facebook profile

Go to the twitter facebook application and wave over settings, the one next to your name.

Choose twitter settings and pop up box with options, select the " Additional Permissions " tab from this box and deselect " Update my status without notifying me. " select OK to confirm.

Tweets will no longer update your facebook.

It should be noted that tweets starting with a reply to somebody eg. @MFtaz should not update your facebook profile, and doesn't usually come up in your followers twitter. having @MFtaz later on in the tweet will update the status.

Just for clarity I have nothing to do with twitter or the twitter application, just that I spent some time working this out so thought I would share.
