Thanks Mongez. Actually 'DoFollow' means there should be no 'rel="nofollow"' attribute, right? I think
Code:
if($vbulletin->options[reldofollowsig] == 'Yes'){
// Ad nofollow
should be
Code:
if($vbulletin->options[reldofollowsig] != 'Yes'){
// Ad no follow
Because the option page says 'DoFollow' and not 'NoFollow'. Anyways, thanks a lot for the plugin. It saved me a lot of time and worries
