I want my forum to be similar to this - http://cubiccastles.forumtl.com/forum

Is it possible to add the /forum at the end without it ever going to portal unless you physically type /portal at the end.
Even if you just type the domain without the /forum it will redirect you to the /forum anyways.

I also don't want "portal" to show in the navigation bar (where home, and search is)

If you want to have the forum load before the portal, you can does this in the administration panel?

How can I do that?

Also, I don't want the "Portal" navigation link to show up in the navigation bar(where home and search is)

You can remove the link here:  AP > Display > Homepage > Headers & Navigation

For the first question:  AP > Display > Homepage >Generalities

It won't let me remove it -

Also, how can I add the /forum?

/forum by activating the portal.

Please post your forum's link.

Yeah, I activated the portal, but the /forum isn't showing up.

Update: I asked the admin of that forum page and this was his reply - "The domain setup should be somewhere in settings. As for the portal navigation, I don't really remember... it was either settings as well or it was done via css. Something like .portal { display: none; }

I tried deleting my portal. Now none of my widgets are showing up.

Update: Widgets was fixed. But still having problems with the portal.
