How to skip registration for forums and websites
It is always a head ache when we search for our information in google and when google send us to the forums or any text oriented website where registration is compulsory.But I have found out a way to cheat the registration system.When google can cache there information without registration than why not us :p .There are setting in the forum script that if the visitor is google bot they wont ask for registration and allow it to crawl through out the pages,as it will help them to gain traffic.If we act like a google bot we can also get such privileges.
• Switch to the Mozilla Firefox and Install the Add on User Agent Switcher
• Now In Tools-> User Agent Switcher -> Edit User Agents
• Now Fill The Following fields properly
Description : Googlebot 2.1 (New version)
User-Agent : Googlebot/2.1 (+http://www.googlebot.com/bot.html)
• Now Goto Tools – > Default User Agent – > GoogleBot 2.1(New Version)
That’s over 
Now Browse like a Google without any barriers.
