Edit the page and add your comment on a new line underneath the previous comment
Indent your response by starting each paragraph of your comment with a colon (:)
For example, on this page (and any other help page), the answers to all of the "frequently asked questions" are indented, by beginning the first line of each paragraph of the answer with a colon
If you are responding to an already-indented response on a talk page, add a colon for each additional, necessary indentation
How can I find out when someone has replied to the message I left another talk page?
When editing the talk page to leave your comment, make sure that the Watch this page checkbox near the bottom of the screen is checked before saving the page
If you forgot to do this, or if you want to be notified of changes to any page, even when you haven't edited it, you can add the page to your watchlist by clicking on the Watch link at the top of the screen when looking at the page
You will be notified whenever the page or its associated talk page changes
An email will be sent to you whenever any page in your watchlist (or its talk page) changes.
Alternatively, you can see which pages in your watchlist have changed since you last visited them by clicking on the My Relate link in the blue bar at the top of the page and selecting "Watchlist"
When will my changes start showing up in searches?
Your changes take effect Immediately
Your changes or additions will show up in Searches the following day
Pages are indexed every night, so if you created a new talk page, made changes to an existing talk page, or added new words on the existing page, they will start showing up in searches the following day
