Would it be somehow possible to "implement" what thread name says?
I would just simply add opponent's name, ideally dropdown menu from userlist, if possible or typed in 'solo' and chose winner. Then somewhere on my profile, I would see my statistics. Opponents stats would be updated as well, if he would be found.
I am not sure, if you have time to implement such feature, but it sounds cool I think.. or add block count.. hmm... )
