Best of x

I just wanted to suggest a feature which would allow to challenge someone to a best of x series of games. I hate playing 10 games with 10 different opponents, Having established beforehand a best of 5 challenge for example, forces the losing side to lose 3 games. So a rage quit after the first defeat would mean 3 losses.
This will allow people who want to change opponents keep doing what they do, and it will make it that much easier for those like me to find each other...

Interesting idea. That's a feature I'd probably use and enjoy. Essentially, it's a mini-tournament for two people.
