Good Lord, seeing that OG thing avatar made me read Aloy's post in a Spartan-like voice.

Question:

Is this forum built from scratch? 

Too bad it isn't V-bulletin like, else we could have used this:

Description

Product Name:
Signature Size Enforcer

Product Description:
Ever get tired of problem users with half-page long signatures and of policing signature size rules by hand? This mod might be just what you are looking for.

This product wraps signatures in a <div> and forces the sig to a maximum height (in pixels) with CSS. If their sig goes over the maximum height, the sig area is limited to the specified height. Optionally, you can choose to have a vertical scroll bar displayed for the overflowing signature.

This product requires no template changes or file modifications at all. It is all done automagically in the plugin.

Contents:
This package includes:
2 Plugin:
"Add CSS code to vBulletin": Adds CSS code to the global CSS header.
"Put Signature in a <div>": Wraps the signature inside a <div> with the CSS class defined above.

1 Phrase:
sigsizecss: holds the CSS code to be added. In this product, it creates a class called "sizedsig" that will be used for the sig <div>

2 Option/Setting:
maxsigsize: (group "Signature Sizing"): This is the maximum size, in pixels, a signature is allowed to grow.

sigsizescroll: (group "Signature Sizing"): [yesno] Option to add scroll bars to the oversized signatures, or to just clip the signature.
