You can post an entirely new set of picks if you want and you can change your picks as many times as you like, just as long as it's before the deadline. I will accept a quoted post stating a wish to switch Bushell with Goff if that's all you want to do.
Now that the official entry list has been published (
here), I'll say that these drivers are the only ones that can be picked. Any other name on a list of picks will be deemed incorrect and will incur a maximum score for that particular race.
The number of posts in the thread won't be an issue for me, I'll just work my way from bottom to top.
