If you can NOT see the list of members on this page:
http://groups.google.com/group/blokes
then you need to set-up a google account. It's easy, and it doesn't
mean you have to use Gmail.
Simply click the "Sign-in" link in the upper right corner of that
webpage, and then select "Create an Account Now".
You will need to provide your current e-mail address, and select a
password. After you have created the account, Google will send you an
e-mail, and you must click the embedded link in that e-mail to verify
that you do, in fact, control that e-mail account.
Then you will be able to see the member list, and have full member
privilages, incuding the ability to post messages to the group.
