OK, so its ages since you posted this message, but as a newbie myself I thought it would be a good exercise! Would this work:
SELECT m_t.member_name, m_t.joined_date, c_t.member_name, c_t.character_type, c_t.character_level FROM m_t, c_t WHERE m_t.member_name=c_t.member_name
(note: m_t=member table, c_t=character table)
This (I think) should produce a table as you wanted.
