I've transcluded Community Messages on the Homepage of my Wiki here, but I'm having some trouble correcting the right border of the box. It seems to be outside the limitations of the right column. I've so far found no way to alter the width of either the right column or the Community Messages box itself. How would I go about fixing this?

Thanks, appreciate it.
