# Revision control TWiki has "Soft security" - anyone can change anything, but changes are logged. There is a complete audit trail: - Version - Date of last revision - Person who made change is recorded. At the footer of each topic one can click on previous versions. One can also see the differences between revisions by clicking on the > sign located between revisions of a topic. [[See More Tips...|Main/TWikiTipsOfTheDay]] -- TWiki:Main.PaulineCheung - 30 Jan 2005
