Checking source page (CTRL + U) on FF, and searching for "nofollow" is the right way to check 'No follow' signature links on Vbulletin forum? G!
I'm using Quirk Search Status addon for Firefox. That is way easier than by looking at the source code.
lolz u guys don't need to that codes just install a add on for Mozilla named no-follow do follow and then just right click on any web page and check no follow or do follow it will tell you in colors whether its do or no follow and its good to check for these coz do follow link is more powerful then no follow!!!!!
