David,
What you are proposing is a discussion group afaics, but more
complicated. It would also be open to spamming I imagine.
The messages coming in through the integration can be moderated to prevent spamming; just as ordinary group messages can be.
For the other people it is simpler than a discussion group: they didn't have to join anything nor deal with extraneous messages (announcements about others). And it isn't that much more complicated for you - set up the integration and after that the group operates in a normal fashion.
The key distinction, over what you're doing, is that the others initiate the messages - which may be a bad thing if you prefer acting as curator and author of the announcements.
The issue is that the others are not specific people who do it regularly. They would not have a clue what this is about, and I would have to explain it to them in detail each time it needed to be done.
I do it as a convenience feature and to minimise the amount of forwarding I have to do. It works well. Anything else would be overkill and take more of my time.
Simple is often the best.
David
