Question

We need to develop a family tree portal which also supports functinality like

1. Portal Framework (Sub portal)
2. Dashboard
3. Blogs, Forums, Events, Polls, Task
4. Member subscription
5. Advertisement
6. Chat
7. Broadcast
8. Document Management
9. Personalization
10. Alerts & Reminders

And above all Family tree

It is also decided to build family tree from scratch and develop UI in Flex.

I am planning to develop it in DNN as i feel other modules are freely available in DNN

Questions

1) Is all listed modules freely available in DNN ...if yes can you provide link? 2) Do i need to consider any other Opensource CMS like umbraco or any other suggestion 3) Very unlikely...But should i develop it from scratch

Limitation : I will not be able to afford costly CMS

Development Platform : ASP .Net 3.5 & SQL Server 2008

Please suggest
