The community decided to work on a brand new website:
The proposed technology is Jekyll but we have also to decide the website template to use.
Muhammed Olgun proposed this approach:
- Find a modern new static site generator like Jekyll 
- Create a template
- Start to use it in a specific path like https://manifoldcf.apache.org/*new*
- Migrate our Forrest xml's to Markdown (we can automate this somehow)
- Start to serve our new site on root path
