Always use Forum URL as Base Path

[stratos]

I had setting "Always use Forum URL as Base Path" to YES
is there a problem (SEO, or what elese?) that I now change it to NO?

I don't use anything the description says..
If the URLs for the different vBulletin components are set below, this option must be set to yes.

Thanks in advanced

Not sure I never changed that, I have always had it set to "Yes".
