Now that you are contributing regularly to the discuss mailing list, maybe you would consider subscribing to it so that all your messages will go directly to the list, and not have to be approved first by one of the moderators.
You can do this easily by sending an empty email from your normal email address to [hidden email]. You'll get an email back which you should reply to, and then you're in. If you later wish to leave, it's the same procedure: you send an email from the same email address to [hidden email]. Once again you'll have to confirm that you want out, but when you've done that, you're out.
