You should try to keep your replies in one threaded message so it's
easier to follow. As of now you have three top-level messages each with
the same subject.

It may be easier you to reply via the archives since you are not
subscribed to the mailing-list:

Choose the appropriate message and then click on the email address of
the person you are replying to (the message will be sent to the
mailing-list). A sane mail client will include the "in-reply-to"
header information.
