Thanks Chris and Mike.
I'm wondering if DNN is the right product for what I do.
The heart of my project is to be implemented with a module, the news are a list of news items with the same page ... So this is also a module (perhaps it already exists).
Articles, these are always the same page and change its contents ... another module.

I do not need the management page of DNN, I saw that Drupal and Joomla are nearest to the following logic: list content > template > display. But is PHP and I'm Microsoft.
SharePoint, I'm Solution Manager SharePoint, is too expensive and I not have sponsor. That nerves!

Someone would have time and want to work with me on the project and develop what need?
The largest Italian portal of marine biology, as I wish in multiple languages ​​and with a certain distribution. Unfortunately I do not have funds, should be a collaborative interest in the project.

Do you know someone expert in DNN that could help me out for free?

Thank you.

Thanks, I'll see your link.
