Setting the portal page as the 'default' page

We've created a homepage using a portal page, and our custom url now directs to this page, however when people log in they get sent to the index not the portal. How can this be changed? I've selected 'the portal' not 'the forum index' under Display>Homepage>Generalities but it doesn't seem to have worked.

Any ideas?

Thanks,

James.

Just to clarify the problem, the following options are in place.





The url takes you to the portal page, which is perfect, but when you log in at takes you to the forum, not the portal. Is there any way to change this?

Sorry to post again but thought this makes it a bit clearer.

Thanks,

James.
