Simply leave a comment here on why you will be deactivating.
eg.
nts_kris:
i will be deactivating because i'm busy with work.
[[ i might be getting a job this summer lolol. ]]

please be noted that you have to comment on here and not on the story.
if you don't, i'm taking it as you're still here, but either way.. you'll be deactivated.
/too lazy to explain.
