You need to create a Menu Item to show it permanently from any of your EP page/Quick Launch Menus (or temporarily just copy the Url and remove everything after .aspx ,you can put this url in address bar to go to the page anytime)
when you create the page, you should save it under EnterprisePortal Library
Then you need to create a Url under AOT > Web > WebMenuItem > Url > Create new
In its properties → URL → select Ellipsis button → Find your page under Enterprise portal
Add it under you Quick Launch Menu. To get to your Quick Launch Menu-> Go to your Web Module → Check for the property Quick Launch
Find the same menu under AOT >Web > Web Menu
I am also a newbie to EP. I have a question which I posted before in this forum , if you have any answer pls post back!
