Yes, I am typing this on my Surface Pro ( original) Touch Keyboard using the Surface Forums app.
It seems to work pretty well.
I just went into the Store and the app doesn't seem to be there.
I just presumed I had gotten the app from the Store but then my old memory kicked in and I realized I have a few apps that I got on the Internet.
Just searched the Internet but didn't find it ... must have used wrong search terms.
Don't know if it is possible to give an app to someone else, if I could I would give it to you.
