thanks for looking into Sitefinity. Is the Chat the only requirement for this portal project?
Sitefinity is a content management platform with a lot of features to create an Intranet or Extranet portal/website, so there are forums, blogs, comment capabilities, full-blown digital asset management features, granular permissions control (so you can assign who has access to what, as you require) and much more. An extensive list of features is available here
. Unfortunately there's no built-in chat feature, but one can be integrated.
I think the best way for me to be able to give you a more accurate answer on how much Sitefinity would be able to address your needs would be if you dropped me an e-mail with more details on your project. You can reach me at firstname.lastname@example.org, add an "Attn: Greg" in the Subject.
Hope that helps!
