[Mailman-Users] Subscribe/Un-Subscribe via e-mail, not web

[Gerry Doyon]

Howdy folks,

I couldn't find my answer in any of the FAQ's or web searches that 
solved my problem.

I would prefer to create some sort of an HTML link on my web site 
which, when clicked, will launch the users on mail software and have 
the Send and Subject line already filled in that will either 
SUBSCRIBE or UNSUBSCRIBE the user.

Can someone please point me to some documentation to do this?  I have 
tried, what seems, endless combinations of parameters/commands in the 
Subject and body of my messages that will subscribe myself to my test 
mailing list, to no avail.

All help is appreciated.  Thanks in advance!

- Gerry
