Forum Moving date / time stamp on thread

[محروم.كوم]

Under "Last Post" there appears the title of the thread. Under that appears the poster's name. Under that appears the date and time stamp.
What I'm doing is by reducing the size of the forum icon and the box it sits in, reducing the size of the forum itself. By doing that I can add a few more forum sections with out having to scroll down the index. It won't be any harder to read since all that's being changed is the size of the field it sits in.
Ok so the problem is because the last post field is 3 text lines high, it's defeating making the forum icon and it's box smaller. (The height of the forum section follows the height of the icon box)

How would I go about moving the date/time stamp up to the right of the poster's name? I know it's probably going to take some sort of template modification. But where and how? __DEFINE_LIKE_SHARE__
