HTML Code to add onto forum:

Code:

<iframe src="//www.google.com/calendar/embed?height=600&wkst=1&bgcolor=%23666666&src=du0f9u3mkat56jan0ctjg3b37k%40group.calendar.google.com&color=%23AB8B00&ctz=America%2FToronto" style=" border-width:0 " width="800" height="600" frameborder="0" scrolling="no"></iframe>

You can add a custom block to your portal and have it there.
Create the custom block -call it google calender or whatever
post that code there.
Modules>portal management

If you want a link on the nav bar for the new calender, you can make a customized menu
Display>headers and navigation> nav links>add new menu

There is also a calender option you can enable on the forum by going to:
Admin Panel>Modules>Calender>Configuration>Activate the topic calender>Yes
