$30 - $250

Project Description:
We have a preliminary draft of a site designed in Drupal at www.neuroncology.net. In one section we have a page with the acces to a private intranet:
The registration and recover pwd links are protected by "areyouhuman" captcha (http://areyouahuman.com/)
However the login page (http://neuroncology.net/content/research-databases) has not integrated the verification code.
We need:
1. either to integrate "areyouhuman" in this page or another captcha verification script but not recaptcha
2. Remove the login intranet box in the top right of all the pages (http://neuroncology.net/home)
3. Suggest and implement the code to track the visited pages and users who visited the site. Either internal or external options are OK.
4. Generate an invoice when the task is completed

Skills required:
CSS, Drupal, HTML, PHP
