With the launch of the new site, we are putting together a mini-tutorial covering questions about the site.
We will continue to add to the site as we receive more questions.
By default this is set to on so you will automatically be subscribed to any Topic you create or post you reply to unless you uncheck it.
If you do not want to auto-subscribe, you will have to change the setting in your Agora profile.
Click on User Profile at top -> On left click Edit Profile -> Settings -> At bottom click Subscription Addon.
Set to option you want.
