What is a good instant messaging service?

There's a new website called, GroupMe https://groupme.com/

It's free to use. The service provides SMS messaging for you to SMS with one or more people (great for a small group). The way it works is that you create a 'group' on the website. Then, you send an SMS from the website to everyone you want to include in the group. They simply click on the message to become part of the group. There is an option that allows you to just SMS with one person in the group.

You can send an SMS to your phone as well. And, everyone in the group can SMS everyone else. When you turn your PC off, the group still stays active.

The GroupMe program is very easy to use. You can pick it up in 5-minutes.

Also, you can have multiple groups
