While a moderator might have started the threads in late March, you will also notice that there was no activity until May or June, because there really is nothing to say until after AMCAS has opened in May and applications are transmitted to schools at the end of June.
The only thing you can possibly do now is maybe prewrite secondaries by looking at what was posted in the beginning of this cycle, and hoping they don't change. You'd literally be talking to yourself if the threads were created now and you started posting. Good luck!!
