Now that YC accepted all 15K companies, it's going to be extremely hard to RSVP for in-person lecture attendance. I tried doing so less than an hour after I received an email with a form to RSVP with no success.

"Thank you for your interest in attending. Unfortunately we've reached capacity for this event."

I understand that this is optional and not required, but with so many companies in, would it be possible to somehow increase the capacity?
