Well, respawn points are where you spawn when you die. If you have a spawn point set to 'Neutral', anyone can spawn there. Set it to 'Attackers' and only one team (the red team or Offense in One-sided games such as One-Flag) will spawn there. The opposite can be said for 'Defenders', which will spawn blue team or defense in One-Sided Objective games. Spawn areas select all the respawn points in the area you select, and set it to the same setting. If you have anymore questions, please don't hesitate to ask. PS, I was not trying be a jerk in that first sentence, simply starting off with a basic fact.
