Thanks! I hate that you have to be watching and claim them... I always forget unless someone reminds me.
What's worse is that it doesn't even always help to watch them. I keep a tab open on the GOG Connect page and click "Refresh" (almost) every day so I don't miss anything. I did that today and it said there were no new games for me. Then I went to the GOG homepage and saw the announcement that were 20 "new" games added to GOG Connect. I went back to my open tab and Refresh still told me there were no new games. So I did a Ctrl-F5 refresh of the page and then the games showed up for me.
Now I'm left wondering if it's any use to keep that tab open that I've had open pretty much since GOG Connect was announced.
