Here are some great tools you can use to get your youth group, small group, or entire congregation talking.
www.todaysmeet.com
TodaysMeet is a great website because it allows you to create an unique backchannel discussion board for any occasion. Just name the room, say how long you want the room to be open, and click create. It will give you a link people can go to where they can give there name, no sign-in required, and then you're off and running.
www.gosoapbox.com
GoSoapBox requires that you set up an account. Once you do there are four main features that GoSoapBox allows you to take advantage of. The audience can ask questions. If somebody sees a question they like they can vote on it. Popular questions rise to the top. There is a place to create discussion boards. The confusion barometer allows the audience to vote if they are understanding the topic or not. You can also create polls for the audience to take.
www.tweetchat.com
TweetChat is great for twitter users. It's pretty simple to use. Go to the website and sign in using your twitter account. Choose a #hashtag to follow. Converse in real time. The most difficult part of this is picking a good hashtag. You want it to be unique and memorable, but not too long because you only have 140 characters to work with.
www.chatzy.com
Chatzy is a cool website I learned from Richard Byrne. Chatzy allows you to create your own chat room, set privacy settings (you can password protect it), and sent out invitations. If you don't want to send out invitations, you can post the link on your website, Facebook, or in your church bulletin.
All of these are great ways to get your church members engaged in the discussion. I have also found that this is a great way to get those quiet ones talking. I hope these helps and if you would like a video demo of any of these websites just say so in the comment section below!
