How can I delete/revert my edition of the OP before or during it is peer-reviewed? Or how can I further edit it while it waits for review? When I try to re-edit it by simply undoing by hand all the changes I proposed, I get the message "Nothing appears to have changed", but that is exactly what I'm looking for!

@Rol What do you mean by "peer reviewed"?

Do you mean a suggested edit?

BTW this room is rather inactive.

You would probably have better change of getting some answer in the main chatroom:

Is perhaps this what you need, @Rol?

Thanks!
