YOu forgot to add where it goes so for those that see this it should go where you want this effect to apply.

@Wrighty you might want to make it o that the old nav menu still shows and that it registers buttons that you have added with code and have it center all the buttons with the forum because when added it pushed them all to the side, also if anything you could make another version of the code that will allow you to reorder the buttons in anyways and allow you to add new buttons.

Edit: also just wondering, if you aint going to do it, could i give it a shot? i'm asking because well everything i'll need to use to do it is coded by you so its the respectful thing to do.

i edit my post above, also at the same time you need to take into consideration that people do use multiple skins so they may use skin headers, for exanmple for my site i have 2 skins so i have a copy of codes for each skin because how they effect the skin directly, so you migtn wnat to add a comment about that as well, because if they are using mutiple skins headers/footers the code would be buggy and not work with the rest...sorry fr be very technical..
