you have entered more than the maximum number of usernames yesterday, sop now you cannot invite anymore until people have declined or accepted your invites.
Help Inviting People to an Invite-Only Tournament

I have a tournament going on for members of one of my groups only. On the tournament page, I go to "Invite a group I manage" and invited that group. I did that yesterday.
Now today, I new member joined and I would like to just invite him to the tournament (without bothering the other members of the group by sending them the invitation twice). I go to "Invite individuals players" and type in his username, and an error comes up saying "Too many usernames entered. Enter in up to -6 usernames comma separated." It says -6 usernames. I can't enter negative six usernames, so I think something went wrong somewhere.
Any idea?
Thanks.
When inviting individuals you are limited to three times the maximum number of players. If this is the tournament then temporarily increase the maximum number of players setting. Invite the new member then return the maximum number of players back to the original number.
