So I could have missed something already on, but besides the private or open option in creating a debate, is there an option to narrow opponents or make it impossible to accept without a second modification? You could kill two birds in one stone by allowing minimum/maximum ELO caps to be set in starting a debate. That would help people who want higher ranking debaters, safeguards against noobsniping, or impossible to accept until PM.
Also, do we have a wikia?
