On vBulletin forums, there are options to indicate to readers whether a post has been "Edited", and readers have the option to view the history of that amended post, the post author also has to key in a reason for amendment.
Suggest that Bitcointalk admins implement a similar mechanism.
As already pointed out by knightdk, the feature is already present.
Example :
https://bitcointalk.org/index.php?topic=211858.msg14967934#msg14967934Do you notice the dotted underline below
Today at 06:16:57 PM? If you hover your mouse over it you will be able to see the time of Last edit.
You will only be able to see the
time of the
last edit made. (IIRC past contents of an edited post and edits made can be viewed by a person with administrative privileges)
However if you made the edit before around 5 minutes after making the post, it will not show up.
Edit : 10 minutes
