[Mailman-Users] Altering "confirm subscription request" pages

[zzizzle.com]

Anyone know how to alter the html of the "confirm subscription request" 
and the "subscription request confirmed" pages?  Please explain in 
simple, non-programmer terms.  I am good at html and flash, but not 
much else :)  If you know of a way to have the user's clicking his 
confirmation link automatically confirm them, and then send them to a 
URL of your own choice, that would be ideal.  I don't like the text the 
system provides.  It's unnecessarily confusing.
Thanks!
