Use the preview button
When editing, use the preview button, and try to do everything in one edit, instead of making excessive minor edits. Otherwise, you'll clog up the recent changes with your edits.
Also, read this. If you make no effort to contribute constructively outside your userpage and the Smash Arena, your userpage will be locked from editing until you do so. Omega Tyrant
