Like vBSEO , how to put the first words of paragraph in the meta description of the showthread?
I found something and was very close, it is to use the value $thread[preview] that is defined in threadbit template ( I have a thread about this that no body answered)
The only thing it is not defined in headinclude template
so the question is : how to define $thread[preview] in the headinclude?
OR
Is there any way to put first 25 word or something in meta descirption not using vBSEO?

note: I asked folks at vbulletin.org even submitted a tickets in vbulletin.com support [the answer was so honest :Sorry I do not know what code modification are required to do this.]
nobody seemed to know how to define $thread[preview] in headinclude
isn't that strange?

*The mast important value for this that in gives higher ctr in search results (preferred by users) and remove short meta description errors in webmaster tools specially for short titled threads.
