I have seen forums do this both ways in the past, but I thought it might warrant a wider discussion.
My question is, when a user posts in a forum which supports signatures, should that signature be appended to their post at the time of their post, locking in their signature at that point in time. The alternative would be to load their signature dynamically each time - meaning the latest signature is always shown...
If the idea of a signature is to emulate the way it works on email, then the former is the way it should be done. I would love to hear peoples ideas on what their preference is and why.
