Last night a new screen landed under the "My bras" menu (don't get too used to this menu, cause it may change soon ).

It is the last item and it is called My participation, this screen will show a summary of the activity you have scattered across the site and never remembered where you put it

Now you can go and check all the comments, votes, suggestions you've made. There was no way to track these before and it's been several times where I've been wanting to go back to a bra I made a comment on and couldn't quite remember which was it.
