[Mailman-Users] Trying to Figure Out (Are Email Commands Adjustable)

[Christopher VanOosterhout]

Greetings,

Is there any reason why the address syntax for the subscribe / unsubscribe 
email commands are not identical?

I am working on a method of subscribing users via my own (guestbook style) 
interface.  The fact that address with subscribe requires 
address=address at host.com and unsubscribe only requires address at host.com

1) Is there a reason for this (functional or otherwise)?

2) Can this be changed in a setting, etc.
