Huge dictionary file, which of course can be changed to anything you want.
Progress tracking, if connection drops and the script has to stop for one reason or another, it'll give you the links that it could find and a progress parameter that you can provide the next time you run the program so you don't have to start from the beginning again.
User can specify the website page extension (.asp, .php etc) to narrow down the search options.
Results can be saved to a text file for future reference, and the user may choose to silence the script so that it doesn't show every link as it tests it.
Ability to pull robots.txt which sometimes might save you having to search the dictionary file as it often contains the link to the panel. The script attempts to parse robots.txt.
self changing user-agent that (a) keeps changing itself so that you don't end up getting blocked and (b) mimics a browser's user-agent to further minimize the chance that you get locked outside

Although Delwar did some of the things I asked he didn't do all of them. I even had to google some examples to send to him so he understood what I wanted done. He told me during the review process that he was an expert in security. An expert would know what needs to be done to secure a form from hackers and spammers without help from me. He also told me he had a good grasp of the English language yet he stated he didn't understand what I wanted numerous times. I will now have to seek more help
