Friend list or Flist as some people call it, to know if your friends are online or not. Player report for anyone you suspect for hacking or abusive behavior.
I agree, a friends list ia an absolute must! As the community grows, this will undoubtedly be a must-have-feature, so we'll be working on this once we've completed the computer opponents.
A player reporting system is also an excellent idea. I will put some thought into how we might implement this.
Thanks for posting!
