After looking at all the team rosters, I can see that the majority will be using their one pre-season Add/Drop this coming week.
I will be posting here on the forum tomorrow morning once the waiver wire has been officially opened.
No, I won't be changing the setting to allow Add/Drops until tomorrow morning at 8:00 AM ET.
If I were change it tonight, any waiver claims put in tonight would go through later tonight(Monday morning at 1:00 AM ET).
Every team will have until Wednesday night to get their one pre-season claim put in before the first results come out. Monday, Tuesday, and Wednesday's claims have results on Thursday at 1:00 AM ET.
