Here you can digest how to use Wikipedia in bite-sized morsels. The tips listed below were created for the Tip of the day project, or the Styletips project, but are listed here by title and organized by subject area for your convenience.
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:
If you want to compare the differences between two revisions of a page, click the history tab at the top of the page, then select two checkboxes to mark the revisions which you want to compare. Alternatively, click the (cur) link to see the differences between a revision and the current (most up-to-date) revision, or the (prev) link to see the differences between a revision and the previous one. You will see two columns of text next to each other, with any changes in red. You can also view the drafts on their own from that page, or change which versions you are comparing. Just be aware that changing templates and images are not recorded.
