If oaN doesn't answer positively for Thursday 22:00, then I think we'd be able to play at that same hour. I'm also asking (just asked minutes ago on our forum) if my mates can play at 19:15 against Crew that same day, so that means we'd have to be sure our matches are finished before playing against another team. 21:30 could be possible, but I prefer to ask 22:00 against oaN since they asked us long time ago.
