subheading help needed

Hi — I used to (in 1.2 or so) have a subheading that worked (using info gleaned from these forums).
Unfortunately after upgrading to a nightly a month or so ago, the structure of the php files changed, so I got rid of it.

Can someone help me? I would like the subheading included in the same box with the header. I’ve never been able to get the whole header to fit in either, so I’ve either got to get rid of some info, or use a smaller font I guess.
