|This page is a guideline on Wikipedia.
Many editors agree with the ideas on this page. It is a good idea to follow it, but it is not policy.
You can change the page as needed, but please use the talk page to make sure that other editors agree with any big changes.
When you change a page, there is a small box with the words "Change summary" under the main change-box. It looks like this:
Whatever you type into this box will show up on the New changes page, in the page revision history, and in the watchlists of users who are watching that article. You can write up to 200 characters there.
It is always good to write something in this box. This lets people know what you have changed. You can also say why you changed something. Some people use abbreviations in their change summary. There is a list of abbreviations used at edit summary legend.
When this box is left blank, the change summary sometimes gets filled in by itself, for example, it may say "Replaced content with (something)". This makes it very easy for others to see if an edit is vandalism and roll it back at once.
