Got you added, Paul.
On finding folks, I have been opening the link posted here in a new tab, then going to the app, touch the world, then type the city, state, or country in and go from there. I have been finding them based on their temp in the bubble, and if it matches whats in the tab, I'll add them.
To add them to the Favorites in the app, touch the correct one, it will show up at the bottom of the map with a camera picture. Touch the picture, and it will go full screen. There should be a blue/white star in the lower right corner. Tap the star and you've added it to the list.
Hope that helps,
John
