Sorry for the long title but I just don't want to ask another "how to lock an issue" which has been answered in the way that does not work for me.
Specifically, I'm editing a description of an issue and I wish to lock it so that no one else can do the same until I unlock it.
Without this, it is hard for the team to synchronize the editing - the description may evolve and change and it has caused headache for us.
Thanks for your help,
