 * Creating non-talk pages

 * Moving pages and files
 * Sending emails to other users
 * Uploading new files (as well as new versions of existing files)
 * Gaining user rights

Autoconfirmed users

 * Editing semi-protected pages
 * Editing sprites
 * Skipping CAPTCHA when adding external links to pages
 * Not be affected by IP-based rate limits
