Hi,
I suggest to make button as title says by clicking it, you could instatly see threads you postded in and another button - threads you started. The most value of this button should be in hand evaluation forums. There are tons of threads made every day, so if you not follow forum for few days, you can miss your posted hands, or discussed other people hands.
Now we can only go page by page to see if they are evaluated, or use search function, enter username, choose subforum and then see, which is lots of steps.
Also, you could add some indicating icon when new of your hands has been evaluated in forum, so you would not need even to click a button.
Or for even more lazy people - make small software which you install on windows (and other OS if some people need), login and it automatically checks if there is new hand evaluations, which would be minimized to system tray and notifies you once there is, so you would not need to even open the forum, until you have new hand evaluations
