I recently added a pages homepage to my site, and I have members asking if it is possible to set it up so that they do not see the homepage but rather go directly to the forum. My short answer to them was just bookmark the forum url. But for curiosity is this even possbile for logged in members to bypass the home page when they visit the site?

There is no built in option to do this, no.

One option is to add guest-only blocks to your Forum Index and then use permissions in those blocks to only display to members. 

This will present the Forum index to registered members while still allowing guests to see additional information.
