Yes, I don't think it's possible- unless you ask a few people to report your questions and then the AB editor may remove them.
Or maybe try emailing theEd and ask for them to be removed.
The best thing may be to select the option ' no more answers required' and then repost all questions in one posting
selecting the option 'no more answers required' does not stop any more answers appearing. It only stops you having email notifications that you have had an answer.
I shouldn't worry about it angiealf, you seem a genuine greenie (newbie) so you'll be forgiven quickly enough (not that it's a problem really) but you'll soon get used to the workings (or not) of this site and its users ;-)
