Thank you!

There's no practical purpose for the crawler. It's more an educational project than anything.

Weird, for some reason your comments are being instantly marked as "dead." I think there's some kind of filter that's tripping out for your account since it's new. I vouched for your two comments so hopefully everyone can see them now, but an admin (i.e. dang?) will need to look into this for a longer term solution.

Thank you sir. Actually my other comments are invisible too. That's weird.
