You are right, the number of points necessary is 500. However, you must take a 10 question test that needs to be vetted by a moderator in order to squash or change from pro to non-pro etc. I am trying to find the link to the application for you and can't find it right away. I'll be back with it, unless someone else can point us to it again.

I tought it was 500, but I see that even if I have 833, I can only reverse pairs, but I cannot squash or change it as pro non pro,
