It is now time to familiarize yourself with hashtag commands, so that you only broadcast a message out to the people you want to receive it, those being the members of your hashtag group. Here’s a quick rundown of the more useful ones:
1. Follow #tag - (example: follow #tip) - lets you follow all updates tagged with #tip.
2. Follow username#tag - subscribe to all updates from a certain person that are sent to a group. (Example: Follow @EricTheBastard#tip will give you every post by @EricTheBastard sent to the #tip group)
3. #tag message - Send a message or question to the group. (Example: #tip Don't set up an automated message with a web address in it.)
4. #tag !message - Send a message only to people who are subscribed to updates from #tag. (Example: #tip !How many tips have you retweeted me today?)
5. Leave #tag - Unsubscribe from the group. If your friends are subscribed to this group as well, you’ll still get messages from them that include updates for the group. (Example: leave #tip will unsubscribe you from the Tips group, but you’ll still get messages from your friend whenever send a message to #tip).
6. Remove #tag Unsubscribe from the group and from friend messages that include this tag.
