1. You have to be logged into Agoracom on the top right of the page
2. On the bottom right of every message is a report violation box and a recommend box. If you click on the recommend box once you will see the number go up by one. You can only recommend a message once.
3. No recommend box shows on your own messages so you can not inadvertently recommend your own messages. Everyone else will have a recommend box when they read your message.
I'm not sure but there may be a restriction on recommending when someone first starts using Agoracom. Not positive about that.
