We've recently added a new feature on Mobot.net - an activity stream in the Mobotnik profiles. You can see your activity stream here when you are signed in to Mobot. This stream shows the kind of things the Mobotniks get up to, such as adding comments, choosing best answers, answering questions, updating the wiki, clicking "have" or "want" on phones or tablets.
Additionally, there's a little notification icon up at the top right - see the little mobile phone mast? If you have new notifications, the mast will show you how many in a little pink box like this >>>
The dropdown will show you the Mobot happenings since you were last signed in, or you can click the link to "view all activity" to see everything.
If you don't yet have an account here on Mobot, feel free to sign up and start commenting!
P.S. We're kind of still in beta as we're constantly adding new features, so if you spot any bugs, please let us know in the comments below.
