I just need to make all the fields in "prefix1_users_table" and "prefix2_users_table" have the same value. They're basically the same table, same structure, but with different prefixes, and for now, different data. The problem is that I have two phpbb forums that share a common database, and I want users registered on one forum to be able to log into the other while keeping the forums and posts separate, so the tables need to be the same, 100% of the time.
