its in the vbulletin options for example if i change my sig. right now it wont show the new sig. on all my old posts but if you press the sig. cache button in the vbulletin it will update all my posts with my new sig...
Your sig from the middle of February... I think there needs to be another few options enabled (or disabled) to make that one relevant. The best it would do would be to turn ON your first two weeks of posts so those would have sigs in them.
I dont really understand what your saying? Also I do know dp updates sigs.. from past posts cause I have seen it first hand Im just curious if there is an average of how often they actually do it..
Automatically... When your browser opens a thread it calls to your profile for your signature. If you change it right now, all of your posts will change, right now.
