having trouble replying to mailing list in Gmail...

[Mike Chalmers]

I think I am doing something wrong. When I reply to an email on a
mailing list I click reply in the bottom left hand corner of Gmail,
from the last person that posted. It then puts only their email in the
"To" box. Then I hit send and it seems to send it to the person
directly. Is there a certain way that I need to reply to emails on a
mailing list or am I doing it correctly?
