The latest software updates were produced in response to a request to support having a separate email list for staying in touch with guests who are not yet members. You can also use it to keep tabs on former members you hope will return someday. This is part of the the integration with the Mailman mailing list utility. The Guests/Former Members tracking screen has also been updated to allow you to add those individuals to the list.
In addition, I’ve made it easier to manage one routine administrative task: approving or deleting messages that have been held for moderation.
The options below will appear on your Toastmasters settings screen if you are running an independent website. If you have one of the free toastmost.org accounts, I have to manually set it up for you (in which case I’d ask you to consider making a donation to the cause).

Simplifying Mailman
Mailman is an open source Linux utility that has been around for years. Once you have recorded your password, the WordPress software will log into Mailman on your behalf to perform routine functions like adding the email addresses of new members to your members email list. The link to the Mailman administration page, along with the password, are also displayed on the dashboard in the section only visible to site managers (officers) and administrators.
This kind of mailing list allows you to write to a single address and have your message distributed to everyone on the list. It includes some basic unsubscribe functionality, and you as the list administrator can also add and drop list members.
As an alternative, the RSVPMaker plugin included as part of WordPress for Toastmasters, supports integration with the MailChimp marketing email service. However, forwarding a message via the Mailman email list is a lot quicker and easier than setting up a MailChimp campaign.
Before distributing a message, Mailman checks to make sure the message was sent by either a member of the list, an administrator, or another email account that has been specifically whitelisted as an approved address. If not, the message will be held for “moderation,” meaning a list administrator has to approve it. This is helpful for preventing spam, but it does add a certain amount of hassle and gives you another password to remember.
The Mailman user interface for that task is not the most user friendly.

Now, when you get the notification about one of these pending messages you can approve it from within the Mailman Mailing List screen in WordPress (under the Users menu, next to Guests/Former Members).

This screen also allows you to view who is currently on each of the 3 supported lists (members, officers, guests) and to add or unsubscribe list members.
Under the Pending Messages section, you will see the email addresses of any unauthorized members who have written to the list, along with the subject line of the message or messages they sent. For each email, you can choose to Always Approve messages (whitelist), Approve Once (just this time), or Blacklist the message. If you approved the message, it will be transmitted. If you choose Blacklist, the message will be deleted and any further messages from that address will be blocked.
You can also click on the message to read its content before deciding, although currently that does require you to log into Mailman directly. Often, it’s pretty obvious from the subject line and the email address, for example if a member is writing from a different email address than the one on the list or if a district officer is trying to write to your club.

Adding Email from RSVPs and Guests/Former Members List
The Guests/Former Members screen automatically tracks information about people who used to be club members (and users of the website) but aren’t anymore. You can also manually add information about guests and former members who you want to stay in touch with. You now have the option of checking off emails from the Guests/Former members list that should be added to your guest email list in Mailman.
If you use RSVPMaker to register guests online, you can also pull in the email addresses people who have visited but not joined your club from those registrations. This is relevant to the online club I helped found, Online Presenters, where we have people register to get the link to the video conference.
Here is a quick video demo of how that works.
