Registration is completely optional and free. The only required field is your email address.  However, there are benefits to registering as a seller.  These benefits include being able to:

1. Manage your postings
2. Renew expired postings
3. Save your default information such as Seller Info, Seller Terms, etc, so as not to have to retype these fields on each posting.  Fill in these fields once and 1804.com will remember this information on all your subsequent postings.
4. Logged in users will not have to reply to an email to confirm each item posted.
