question with form_open

[eluser]thebwit[/eluser]
So I just figured out the form helper but I am having an issue.

All of my url's are re-written in that I removed the index.php from the URL. Yet when I use form_open() it puts it in there.

I have been trying to figure out how to remove it as I don't want index.php in any of my urls.

Thanks for the help with this.
