Free TTN Tip! As TTN grows you will want to get in the habit of creating hashtags in your posts. You can think of a hashtag as an indexing tool. By placing a # before any word, I can assign my post to an index of sorts. For example, If I want to post music I can add a "#songs" or "#music" in the text of my post. Now whenever someone searches for #songs or #music in the search bar, my post will be listed along with anyone else who used the same hashtag.
