How can I tell if someone replies to my post?
When you create a new thread or respond to an existing one, you're automatically subscribed to that thread by default. You should get an email and see a notification at the top of the Boost Community window if someone replies.
You should also see an envelope icon in the notification area and get an email if someone sends you or responds to a private message.
If you are not receiving notifications, you may want to check your notification settings here: Notification Settings page
