Signature Changes
 

Hey, I'm pretty new to vBulletin and have a question on the signatures. I've spoken with the members of my site and it seems that they don't want their old posts with their old signatures to be updated with the new sigs once their changed.

Example:
Post 8 - Sig is: "Hey Everyone!"
Post 34 - Sig is: "OMG my sig!"

When they change the sig to "OMG my sig!" They want posts 8-33 to still display the way the old sig looked, "Hey Everyone!"

Is there a way to do this? Did I even make sense? Thanks for the help (hopefully). ;)
