Add users to topic in private category

[mcwumbly (Dave McClure)]

Ideally, Private Messages to a group would be to the group, not the expanded list of users within that group:

Private messages to a group, or other means to handle private support requests

OK - so on to my ideal workflow:
…

• support as a non-expanded* group would be the recipient
• their ‘account’ group** would also be a recipient
• they would be able to add/remove additional recipients and write/send their message

…

*Non-expanded group

Support is copied on these messages as a non-expanded group
These messages are visible to the new members of this group
Members of this group can control how they are notified of messages in this group, with defaults
notify me of new messages to support
only notify me of responses to messages that I am copied on personallyif unchecked, you will be notified of all responses to messages in this group
