Just a suggestion - if you guys know that you won't have the numbers for the match you may aswell inform the Referee that's in charge of your match so you won't have to take a lose because you'll just stand there having like 3-4 guys attending instead of the required number. I'm certain that with a bit of discussion you can reschedule your matches if you do it quick enough.
5. If you need to cancel a match, simply Quote your match post on the forums, and type "Cancelled" underneath it, this will be allowed as long as it not within 30 minutes of the match start. I will only be allowing rescheduling once, otherwise it will take too long. Make sure you be courteous and let the staff involved know as well. (Referee, YouTuber, Streamer).
