When you do google searches, always put in -notpron to avoid spoilers.
- All levels with a google bar potentially require googling. So use the built in google. About all passworded riddles: - No spaces - No capital letters - You don't need to register anywhere - Do not use Chrome, Opera or Vivaldi; use Firefox, Safari, Edge or IE instead - You will find the username and password written somewhere in the riddle in a hidden way (very different in every level) - No guessing! You will know when you have the answer. No need to enter random words that you find somewhere. - A slow internet connection can cause a correct password combination to be refused. When you KNOW that you have the right one and it's not working, try it again until it works.
Other: - don't hesitate to use external programs to solve riddles, some even require it (all you need can be legally downloaded somewhere) - the only rule is NOT to search for solutions on the web, but google gets you other useful hints if you look for the right things Official IRC channel: quakenet #notpron Forums (spoilerfree, just hints)
