i.e. new timeline is...
Now: You can create accounts and fill in the online forms.
January 26th: You can no longer create accounts but can still fill in the online forms.
February 16th: You can start to submit the online forms and pay.
March 31st: You can no longer submit anything (but it's likely the cap will be full long before this date anyway).
