|Flipping the pages..|
Once you have signed in, a new content square will be added called Google Reader. Tap this square and it will bring you into the Google Reader main view. From here, you can browse all of the latest news from the RSS feeds you subscribe to in Google Reader by simply flipping through it.
To get only your wargaming content (assuming you have other) tap on the Google Reader text in the Flipboard menu bar. Now go to subscriptions and pick the folder you use for wargaming feeds . It now generates your new magazine and takes you to that section. Now tap the + sign on the left to save your magazine as a section.
It probably is quicker to do than to read this.
Note for Google Blogger users. You will have a folder Blogs I am following in Google Reader. This folder for unknown reasons did not work for me. I created a new folder and put all my subscriptions (including blogger ones) in there. All subscriptions will go to that folder in the future...
