Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Go to "https://twitter.com/search/realtime?q=%23TeamFollowBack&src=hash" and then copy al the text on the page. If you scroll down the page will be bigger. Then put al the text in a text file called twit.txt

If you follow the user there is a high probability the users give you follow back.

To follow all the users you can use an iMacros script.

if lynx --dump http://twitter.com/xmuda | grep -q "Sorry, that page does"; then echo "Dont Exist"; else echo "Exist"; fi
