hello there peter i don't tend watch other users talk pages since my watchlist is already quite stuffed and because some talk pages receive a lot of non to related traffic that would cause the page to pop up just a note for the ps section there are multiple ways to post reactions to multiple people personally i prefer to copy n paste the entire section back and forth between pages since that assures that the conversation is always up to date and readable for everyone whereas only placing responses on other people's talk pages would lead to a fragmented conversation other editors prefer other methods some just post a reply on every involved parties talk page alternatively you can place the talkback template on another users page to notify them that you left a response for them on your own page which is convenient in its own rights since you can keep the entire conversation on a single page all methods are really fine in the end it is just a means to make sure that another editor managed to find your reply contact me contribs
