I am Ilkyoo Choi, the organizer of the Carnegie Mellon Competitions. I have been getting several emails about competitors not knowing his/her WCA ID. I was able to tell the person's WCA ID by looking at the URL of his/her WCA page, but I guess non-technical people do not recognize this.
I remember the WCA ID being right next to the competitor's name, but I noticed that this field has disappeared. I think this should be restored..
Maybe I missed some post asserting to get rid of the WCA ID on each competitor's page?
Thank you, Ilkyoo Choi.
