We have a large number of users who only need to login to a site to view a membership directory. For everything else no login is required so they rarely need to login. Only a few people, editors, have special privileges and need to have their own ID's. Everyone else shares a common login ID.
The problem is that if someone logs in with that common ID and then makes a donation, anyone who does that in the future will find the donation form pre-filled with the previous donor's name, address, etc. Is there a way to 1) turn that feature off for a specific ID, or 2) to turn it off for everyone, or 3) to tell when someone has made a donation while logged on with the common ID and to delete that information?
