Also, depending on the number of permissions you are tracking, you could
use a single INT field and do bitwise ORing in your application to
determine permission checks...

of those should work. I don't know your table structure, so I can't

Is it legal to do multiple joins like this?
Thanks
Steffan
forum_messages does not take part in any selection or any where clause.
You have 5 tables listed, with only 4 of them appearing in 2 disjointed,
and improperly formed joins.
From the comma separated table list after a LE
egal to do multiple joins like this?
Thanks
Steffan
