To create this forum on your server, you will need to create a Microsoft Access Database named
discuss.mdb. You will also need to create a single table in this database named messages that has the
following fields:

m_id -- An autonumber field
m_email -- A text field
m_subject -- A text field
m_message -- A Memo field
m_entrydate -- A Date/Time field with default value of NOW()
m_numReplies -- A Number field with default value of 0
m_reply -- A Number field with default value of -1
