They should generally use the basic IGate algorithm, no white or  
black lists.  That is, if the IGate hears a station on RF in the last  
half hour or so (can't remember the exact time), and sees a message  
on the internet stream with that station as a destination, it  
automatically gates it.

That lets travelers use the network and keeps people from adding  
another IGate to solve what they think is a problem with a broken IGate.

I've seen a bunch of very strangely configured infrastructure lately  
- for instance, digis set with aliases of WIDE2-2, so they *only*  
digipeated paths with WIDE2-2 (not WIDE2-1 or WIDE1-1!).  This kind  
of thing breaks the network, although I'm sure it isn't done  
intentionally to break things - it just happens to.

It would be great if there were some basic how-tos on configuring  
digis and IGates.  I know Bob has a bunch of info on his site, but it  
is hard to find and just covers digis (I think) and doesn't include  
UIView (which seems to me to be the most commonly misconfigured IGate  
and/or Digi).
