User Activity

I have used promotional flyers before, but when I manually try to change the items for sale, the system does not accept my 'add' and nothing appears on my flyer. I can't understand why it is not working now. Any ideas?
Do fixed price items show up in searches?
I have put $0 in the postage section, but I would like to have the "Free Postage" Banner across my picture. How can I do this?
I have one specific product for my current user name. However, I want to start another small project which needs a different name. Is it possible to have two different accounts with payment through to my one Paypal account.
