as always, it depends on the budget. The most successful portals out there were not built on pre-packed solutions but are unique systems which focus solely on the group of people it was intended for.

Furthermore, you may want to invest a lot of time into determining what your group wants and how they want it conveyed to them. I am addressing issues like usability, etc.

Then of course you have the aspect of user and traffic load. Can the portal be handled by a dedicated server or do you have to move on to a data centre?

Issues over issues there, as you see
