interaction

Hi All;

I have been trying to setup a "learning section" for a website dedicated to the education if professional oncologists and have been using Drupal with fairly good results, however, I have a problem when it comes to the testing, scoring, examinations and general user interaction/contributions. There appears to be nothing available that will handle quizzes, exams etc. other than the 'Quiz' module [which works very nicely - for what it does].

We are going to launch a new travel website.

Let us know if you see any bugs.

It's the first stage of the project and we are looking to increase interaction with the readers. Do you have any User Generated Content suggestions?
We were thinking of uploading photos, posting stories and blogs, sharing tips and advice...
Please feel free to share your views below.

Thanks
