The admins of each league should take a few minutes to view their weekly time links to determine the best time to schedule any and every event, however, if a player is not able to play in a tourney and feels that a time might be better for all players concerned, then they should contact first the HA of the league and make a suggestion, as well as maybe copying the Events Director at email@example.com.
That is the only way that anything will ever be considered as that is the only true way for all parties to take every possible situation into account. When something is posted in clubs, regardless of what it is, if it is a suggestion, it will spawn multiple threads and will not stay on one thread, and then causes mass confusion, more complaints, and people feeling like they are not getting answered.
As a soon to be former admin, I personally spent a lot of time coordinating events for when our players were showing the most activity, and that resulted in successful events, and happy players (when they showed up after registering).
If you have suggestions, again, the suggestion is to email the events director at firstname.lastname@example.org.
