How do you delete off a discussion ....

you cannot delete any discussions you have made here. probably mylot will in due time. by the way, if your discussion did not get any response, it doesn't mean that it won't get any response in the future. thats why we need to tag our posts for that purpose.

Im afraid you cant, once you have made a post you are not able to edit or delete it, i think its an option that may be added in the future at least i hope it will as i make so many typos i would love to be able to edit, but for now we just have to live with it, btw just because you have posts with no responses now, doesnt mean they wont get responses in teh future
