I've used and shared a few similar tools on here such as Social Lead Fox and Social Lead Freak.
FB Lead Chef has similar functions to these Social ID/Email scrapers however I do like having the option to scrape the details of influential and active users (*Passionate Members and *Power-players) on FB Event pages and in Groups.
Install: To install just run and when prompted to enter serial enter any digits in this format XXXX-XXXX-XXXX-XXXX-XXXX
Enjoy, and mirrors would be good
(*eSafe lists "Virus in password protected archive" - Looked it up and it seems like it occurs when it assumes installer is password protected and returns the alert. The zip is not password protected though - False positive. Nevertheless, always scan D/L's on your PC before you install)
*Edit - the culprit is wyUpdate.exe, which is an open source updater. You can delete this from the install folder.
