Template:How to Preview

Multiple edits
Hello! I noticed you've been making a lot of edits to the same page over a short time. Doing this puts a large strain on our server and clogs up the recent changes. So instead of saving a lot, use the "show preview" button next to the "save page" button. It'll allow you to view your edit for any mistakes so you don't have to make a lot of fixing edits or additional ones, okay?

Usage
Use this template when you notice someone making a lot of edits to the same page over a short time. To place it, type ~ to place the template and your signature on the talk page of the user.
