VBulletin Meta 'Description'

How am I suppose to affect the meta description of my forum? Currently, Google is pulling off a text in my forum's footer to display it as meta description.

You've got some serious template issues if you're getting footer text as a meta description

Any idea as to what is going wrong and where?

Try running your site through a HTML validation checker. However, one way you may be able to alter your search snippets is to make use of our Relevant Replacements feature to add descriptive text for every page, specific to individual content, at the top of each page in an area that is likely to be picked up as first text by Google et al.
