[PLUG] Browser Blues - ALMOST Resolved

[Michael M.]

Thanks ... it's much rougher to deal with than I expected, but I guess I 
didn't really have any particular idea of what to expect.  Turns out you 
really can't prepare for things like this, however apparent it is that 
it's going to happen in the not-too-distant future.

I'll make a separate post about the IPv6 thing.  I didn't mean to sound 
all mysterious, I've just not had time or inclination to deal with these 
things recently.  And I don't know how helpful it will be anyway.  But I 
could use some distractions now!
