We don't need to PM you anything about this - read the 1st post of this thread, all you need to know is there, as clear as it can possibly be.
Copy-paste that little phrase in code to your post, and include there the account that you will use (among the other important details there, of course). Otherwise we will not accept any other type of confirmation and we will not be able to allow you to race tomorrow.
On another note - the first deadline has expired, any other confirms posted after post 28 will suffer a 5-place grid penalty for the race. This thread will be officially closed once Qualifying begins at 16:30 UTC of October 27 and no more confirms will be accepted.
