Unable (?) to subscribe to <address@hidden>

[Steve Ross]

Hi All,
How do I subscribe to the mailing list <address@hidden>?
I have gone (twice over the past couple of weeks) to the subscription page at 
<https://lists.gnu.org/mailman/listinfo/groff/> and subscribed, but have not 
received any of the subsequent e-mails.
What am I missing?  Am I on the subscriber list?  (To my knowledge, I don't 
have an e-mail filters in place on my end that would filter out a post.)
Sorry to spam the list with an administrative question...
Thanks,-- Steve Ross
