@tinabing,
here are the basic rules for post deleting as I understand them.
unless the post is going to cause a death, or ruin someone's life forever, or risk national security (this one may be moot now that the NSA reads everything anyway first) it is probably not going to make the cut.
and the more you post about deleting it, the more likely other folks are to find it.
good luck.
