I have built our intranet portal using SharePoint 2010. The total number of employees to access the site is 400+. In our portal we have done lot of customization using visual studio .net. Since the number of employees increased in the organization and we are not in a position to pay a huge amount as it is license based, we are looking for other tools. The question that i have is that, can DNN allows for customization as SharePoint or not? based on this, we plan to go forward. Please help me with this.

Thanks in advance.
