Conditional Signatures.

Would this mod suffice for now instead of the condition signatures thats not available for the time being.

Show signature restriction. - vBulletin.org Forum

Would you say this is seo friendly....

I just deleted the guest message and set post count to one to disable signatures for guests.

I would say that this is quite different from our conditional signatures because that is only for users over X amount of posts. We take in the quality and length of the actual post. I personally cannot say whether this is bad for SEO though.

I had manually added a conditional in 3.8.5 and am having tough time getting sigs turned off for guests in 4.0.3 I understand that vBSEOs signature product is not working? Can you help us add the conditional to postbit?

You can simply wrap the sig area in the postbit with
<vb:if condition="$show['member']">
sig stuff
</vb:if>
