For some reason I cannot reply in that thread. I was going to suggest that it remain an initial post with the current list and once a month all subsequent posts are wiped and the first post gets updated. Of course if nobody else can post there either it makes the suggestion rather moot.
I have manged to learn several new skills since .4 but have not discovered any means to practice them. These include pottery, painting, musical instrument, baking, body development and empathy. possibly one or two more. Ah yes, anti-magic. Of course I have not made a particular effort to find these just learning whatever I came across that I didn't already know.
