I just thought of a 'steve' rule::::
If phpbb base runs it certain way, then there must be a darn good reason for us to change it, because:
(a) people who visit other sites are used to see it in a certain way
and
(b) the less mod we do to the base code, the less problem in upgrading to new versions, etc.
So 'steve' rule says, there should be a VERY GOOD reason to deviate from the base standard, otherwise stick to it.
