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

What others think

Out of curiosity, why a sleep 2 after all the commands that actually do anything?

@TheMightyBuzzard: It's because sometimes the command loads and executes so quickly that the key-release after hitting the enter key will signal X that the keyboard is in use, causing the screen to turn back on.

@TheMightyBuzzard: Actually, I didn't read the command before replying. The "sleep 2" is so that the while loop doesn't take up 100% of the CPU time.
