This is a public forum, anything you post is for the public and an historical record.
Allowing deletion of posts destroys any sense of the forum.
In the case of anything that you feel does require deletion, then ask the moderators - but you need to have a VERY good reason, and for the moderator to agree with you.
yeah, it's a public forum , but if you add anything by mistake, a reply to a thread, we can only watch it and can't delete it. Sleep Mode PIC microcontrollers - Explanation !! check this site, it has one, it's like a clone of our site.
