Have you ever needed to post an important message to all editors about an article, on the article itself, but thought it would stick out like a sore thumb and ruin the article if you did? Are you reverting many edits on an article because editors just aren't seeing the important message or special instructions on the talk page?
The solution is that you can insert hidden text in the article! That way, only the people editing the page will see your message! Here is how to insert a hidden comment:
First, begin the comment by typing <!--
Once you have done that, type what you need the editors to read
Then, end the comment by typing -->
Once you have completed those 3 easy steps, you won't be reverting as many mistakes!
For example, the following hidden comment has been used in the Meaning of life article, in the Popular views section:
<!--Please do not add 42 in this section. It is covered under the section titled "Popular culture treatments". Thank you.-->
Some more examples of pages that have hidden messages include:
To see a list of a user's contributions, go to their user page or user talk page. When you do that, the menu item "User contributions" will appear in the Toolbox menu on the sidebar. This link will show you all the edits that user has ever made (except deleted edits), up to 500 per page. This is useful for tracking vandalism in progress.
Edits with a "top" link are the most recent ones to their respective articles.
You have your own contributions list, which is particularly useful for tracking your conversations on talk pages. If you are logged in, you can access the list from the "Contributions" link at the top of the page.
To help keep track of your discussions on talk pages, you may wish to place the {{Discussion tracker}} template to your talk page.
