Latest update doesn't show in Facebook Twitter Feed

Hi all,
Not sure if this is the right place to post this, but I am using Twitterfeed.com to post anything from my forum to Twitter and to my Facebook page.
Question is how do I get the latest post to show rather than the start of the thread?
I hope someone can help or point me in the right direction?
Many Thanks
Andy

Think you just have to you set the forums
Sort the posts of a topic by :
Post Date (Most recent first)

Go to admin panel>general>Forums

then click on the gear icon of the forum and at the top of the page bottom of the list you will see Sort the posts of a topic by : set that to Post Date (Most recent first) and hit save.

keep in mind you would have to do this for all forums you wish to have this way, and that it will now show Post Date (Most recent first) in the threads of the forums you set it to.
