Hello fellow Basecamp user Automatic check-ins are the killer feature for me. Nothing like getting the pulse of your team at regular intervals

As for your question, my first thought was Discourse. It's a modern day forum. Posts, threads, the whole shebang. Has badges and leaderboards too.

I've heard good things about Twist as well. Though I haven't used it yet.
