This is a notification that appears as the current BBT trophy is about to end, and you have teams that have participated during the season.

The Steel Gauntlet is a playoff-tournament that (somewhat simplified) takes place after each season for the most successful teams for each roster.

In order to have a chance to be accepted into the playoff, you must mark each team willing to accept a spot as such in the "My Squads" panel of the Blackbox Trophy page. Leaving it undecided (the default) will eventually count as a decline of a spot should it be offered to the team.

Further details regarding the qualifier system can be found under the Team Standings panel (also on the Blackbox Trophy page).

You currently have Blackbox Trophy teams that are opted in for a chance at a Steel Gauntlet playoff spot. At least one of these teams is still in post-match status, which must be resolved prior to the end of the season. Teams that are not in "Ready to Play" or "Waiting for Tournament" status will forfeit their spots in the tournament.
