Added a Trades feed.  You can enter your trades that you want to share with others.  It will add an entry to the public main feed and individual symbol feeds.

You can get to this (at the moment) via the footer or the Create button on main feed.

We'll add this to more places around the site so that you can see what people are trading. 

 It's also quite basic in its current form, more to come.  Lots of interesting things we can do with this once we have trades being entered.
