I bought the vBulletin license in Feb 2011.
I haven't used vBulletin for some months now and I don't see myself needing it any time soon.
So I am selling my vBulletin 4.X Forum Classic license.
It says "Expiry Date: None" if that is of any help.
I am not sure how to verify this license, as I have seen other do in their posts, so let me know and I'll make it happen
I am selling it for 145 USD, wish means you save a bit over 25% off the original price.
Let me know if you are interested via PM or reply to this post.
