Should I be using InnoDB tables, is there a way to switch storage type
at the command line, because my phpmyadmin, shows that the InnoDB is
loaded but not a valid choice for choosing as a storage engine type.

Can anyone recomend what type of storage engine to use. Everything I
have read says to use referential integrity and I am trying to keep
this enforced. Is this not that important?

Sorry for the newbie questions, I just want to do what is best in the
long run.

Thanks
Yanks
