Revert and Respond

It really bothers me when I get emails where the closing line says something like "please revert on this". What most people think they are saying by this is that they would like you to respond to something. What most people don't realize however, is that they are actually asking you "to go back to an earlier condition".

re⋅vert: 

1.	to return to a former habit, practice, belief, condition, etc.:They reverted to the ways of their forefathers.

2.	Law. to go back to or return to the former owner or to his or her heirs.

3.	Biology. to return to an earlier or primitive type.

4.	to go back in thought or discussion: He constantly reverted to his childhood.

and it does not mean 'to respond'.

So the funny ones are when people write something like "please move forward on this and revert right away" which rather confusingly translates into "please take a step forward and take a step backwards right away".

Eventually the usage of the term revert will become universally incorrect and then it will take on a new meaning "to respond", but till then it would be nice if people used it correctly.
