Different front page node depending on logged in? How would I go about displaying a different front page node depending on if the user is logged in or not.

For example when a user is not logged in, you would be viewing the About Page.
When a user is logged in, you would be viewing your user profile page.
There is several solutions to go about this

but the easy way out is this module

Frontpage module

but you can also make a simple  rule that says that if the user is logged in

Rules module

Node.js Alternativ solution

hope it helps you on the way
