dofollow for particular usergroup

Does vbseo have any feature to allow do-follow links in thread and sign only for particular usergroup ?

If so, please mention it.

Hello Siva,

Welcome to vBSEO.

For user profiles, there's no such a feature, in fact, "dofollow" tag doesn't even exist. What you want to achieve needs to be done by modifying the vBulletin/vBSEO code base.

In regards of the signatures, there's an independent add-on called "vBSEO Conditional Signatures" that works with vBulletin 3.x.x series only. If you are running vBulletin 4, you may need to make it compatible with vBulletin 4.x.x series before you can use it.
