User Agent Switcher
[imported from Bloglines]
Is very useful for those forums which let you browse the forum if you’re a bot, e.g. googlebot.. but try to force you to register otherwise..
Just switch your user agent to something like “Googlebot/2.1 (+http://www.google.com/bot.html)” and you’re in.
Just be weary of abusing this because administrators are likely to limit the Googlebot access further by IP or something.
