Do you have permission from the forum owner to do what you are attempting to do? Most forum owners would not appreciate the kind of load your script would put on their system. Many forum owners have filters in place to prevent robots like these. You would most likely get your account revoked and a nasty curse placed on your children.

If you can convince the forum owners of a legitimate need they can probably give you direct access to their database. This puts a lesser load on their servers and offers you more options for searching/retrieving.

I am sorry to say that your code is a mess. I don't know where to start. I think that you are biteing off too much at once. I would start with some simpler tasks. Like, just grab one page and print it. You should also write separate little programs to test your subroutines before using them, so that you know if the parameters are passed correctly.

The text you posted here contained double breaks which made the post display funny. Use paragraphs <p> instead.

In spite of the rain I put on your parade we appreciate your participation in our site and hope you continue to visit.
