If a user has already started a chat with the bot, they do not subsequently send the /start message and hence are not detected as new users. This should not be an issue since the modification to store persistent users but previous users need to send /start manually.
There could (should?) be a mechanism to detect any message, e.g. `/begin' and add the user if they don't already exist.
