Nice tip Plkracer... I've adjusted the the amount of smilies from five columns to three. The problem is with the wide smilies,

for example causes the columns to be extended.
I can adjust the smilie columns down to two. That should fix the width issue for lower resolutions.
This issue should be fixed with the new template coming out soon. This one will remain default but users will be able to select the other style. Should be completed in the next two weeks. The next template from there will be a one off custom designed specifically for
MBN by a professional company.
