[Mailman-Users] Message HTML/Plain text. Wish client display HTML when possible

[Thomas Carpentier]

Thanks all for your explanations. I'll probably go for two lists.

Do you know if there's a php script that permits to send commands to mailman ?

My idea is the following: A page web where we can choose HTML or text 
on registration, like 
http://registration.euro.apple.com/applenews/uk/subscribe/ and an 
update page to modify the choice.
