Let me explain, in a chess.com team match when it says ask an admin, it means the other team admins will decide when the match starts.
Start date: Ask an Admin???

By locking their side when they think they have enough players, then your team will also need to lock your side, so that the match starts.

When a challenger doesn't define the start date while issuing a team match challenge; it appears as 'Ask an Admin'.
There are two ways to start the match...
1. If the challenger has defined a maximum number of players while issuing a team match challenge and 'Auto-Start' is On, then the match starts AUTOMATICALLY when the lineup reaches that number on both sides.
2. If the maximum number of players hasn't been defined while issuing a team match challenge, then the admins of both clubs need to 'Lock Registration' to start the match MANUALLY once they're satisfied with their own clubs's lineup.
Some team matches have a start date. Others tell me to ask an admin. Why don't all team matches set a start date? How can I plan for a start date if one isn't given? I'm not referring to tournaments, just team matches. (If I've posted this to the wrong forum, please forgive me and recommend the proper forum.)
