no it is not fixed in the vbulletin,. everything width can be changed through the styles. Also that was not what mike saying.. he was asking..
Well, if you look at the vB code - the width is fixed in the templates; how did you handle the vb templates?
and I'm saying through the style options where you can change the width varibles with in vbulletin
Mike needs to use one of the varbiles in the style options,..
In fact I just went ahead and found the one he needs to use
In style varible options under Sizes and Dimensions there is a varible called:
Message Area Width (pixels)
(This value allows you to specify the width in pixels of the text box used for all message posting in vBulletin)
Mike needs to use that varible in the pp vb
hope that helps
the image attached you can see the option on the bottom
