Forum Help - Position of User info in Thread

[محروم.كوم]

I just upgrade my vb into vbulletin 4.2.0_PL3. My question : currently the set up of information user and avatar is in the center and then the thread news in after (or below) the user information. How to change the user information, avatar, reputation back to the left side while the thread content is in the right side? Just exactly like this thread user position. Thanks a lot in advance. __DEFINE_LIKE_SHARE__
