Is it even worth it to buy VBSEO if you have version 4.X?
 

I've been out of the forum game for a few years. Last time I had VB 3.X and VBSEO. I noticed with the new version of VB 4.X that the URL of thread automatically incorporate thread titles (which is one of the benefits of VBSEO). I suppose the other benefit was the daily update it sends to search engines, which I assume a hack is already out there which can do the same.

So, still worth it to buy VBSEO for VB 4.X? Will a version of VBSEO purchased a year ago and worked on VB 3.X also work on VB 4.X or do I have to buy it all over again?

Thanks
