Need help specify thread meta descrition length

[nhatnamsj]

Hi everyone, I am new to vbulletin and I am currently using vbullletin 4.0.7. I just checked the header of one the web pages of my website and found out the following:

meta name="description" content="What information do we collect?

I think this is not good in term of seo. I would like to know if there is an option in admin control panel to specify the length of the thread meta description, and merge multiple lines into single line.

Thanks for reading my post
