World Finals is near us once again and I am trying to collect data about participants once again. This year we are able to collect your Codeforces and TopCoder handles through icpc.baylor.edu profiles. If you'd log in into the site and go Profile -> Social Media you'd be able to enter your handles. I would kindly request everyone to do just that.
I'll publish data I gathered in a couple of days, if you notice any errors I'd appreciate if you post about them either in comments to this post or in personal messages
