Positions and regions
How to describe the roles you actually queue and the hours you can play.
Positions are preferences, not a contract
Pick one or two of goalkeeper, defender, midfielder, winger, and striker. Captains filter the board with those words. If you can cover a second role, list it. If you cannot, leave it off.
Rematch is cross-play. Platform is optional context for voice and parties. It is not a matchmaking gate.
Regions are scheduling buckets
The region list is a community convenience for ping and clock time. It is not an official ranked server list, and Arena does not check where your machine really is.
Availability is a coarse window: weekday evenings, weekends, late night, or flexible. Put the awkward detail in the note, in your own words.
