Hi, Steven;

Thanks for your reply.

I am now at the point of trying to figure out how to specify an SMTP
server to ship e-mail confirmations out to new users.  I am having the
same problem as has now clearly been the one, and only one, all along,
which is a lack of logically written and comprehensive documentation.

For example, one of the very first bits of information I obtained was
the importance of getting iptables up and running correctly before
installing WiFiDog.  I spent probably something like 15-20 hours (I
don't give up easily) only to find out after a lot searching and beating
my head on the wall that, hey, WiFiDog writes its own!  

It would make sense to include that snippet of info in the instruction,
cryptic one too, about getting iptables up.  It now appears to me that
the only iptables setup required is to bridge two NICs.  WiFiDog does
the rest... except for refinements as you noted.

Thanks again for your help.  I think I almost have a working hotspot.
Now if I could just figure out where to specify a SMTP server ....

Best regards,
