Navbar button spacing on punBB.

On my forum (link: http://mw2hq.forumotion.net/index.htm) I uploaded a (very wide) navbar that would stretch onto two lines, so I expanded the width of my forum to 105% and it all fitted onto one line. Only problem is, I still have gaps between buttons on my forum. I tried to use some topics already posted here, such as one for Invision, but none appeared to apply for myBB.
Any ideas?

Cold.

Code:

a.mainmenu {
margin-right : -5px !important;
}

Add this code to your css. See if it helps.

i think this may help:

Admin panel>Display>Headers and Navigation

Much appreciated Sanket. Problem solved.

Request for lock.
