About a year ago I created a facebook account using my email address. However I never used it and my husband wanted one so I changed the email address on the account to my husbands email address.
Now I am thinking of setting up my own account but when I try to do it it says "There is an existing account asssociated with this email address".
I've not tried it, but if you click on account in the top right in facebook then select account settings and then click on the email link you can remove any emails associated with that account (apart from the one set as a contact email)
Try removing the original address and see if it lets you sign up again with it.
One more question - Does it automatically set me at the highest privacy setting (ie to make sure that the world and his wife don't see my details) or will I need to set that up?
