A point of information for E-mail threads.
There is a long standing convention that if you are changing the topic
of an e-mail thread, then the person changing the topic should change the subject with the old topic in parenthesis as above.
When replying to such a thread, the people replying are supposed to remove the text in the parenthesis including the parenthesis.
Most e-mail clients and e-mail archives like the one groups.io uses understand this and when set in threaded mode this allows the reader to follow threads properly.
Threads are generally not grouped by the subject text. Threads are grouped by a unique message ID that was generated by the first message in the thread. So even changing the title may not change the thread, and may cause your messages to be harder to find.
Which means if you are starting a new topic, you should start a new message, instead of replying to an existing message.
This will keep the users who have messages sorted by threads and any public e-mail archive properly organized and easy to look up messages in.
