Well you must have committed some mistake in entering your email. Everyone got their login emails who registered. Instead of bashing the project, maybe look at your side and maybe there might be a chance you are the one who is wrong. If you didn't get login mail, why do you care about being the tournament a shitty organize? They are handling the project to the best of their capabilities and i appreciate doing them mistakes so they actually are able to contemplate such problems when their platform goes live in the next 40 days!

In case you have issues, write clearly about what bugged you in the platform, challenges and engage in a healthy discussion. Bashing a project wont let you do any good nor the project!
Peace!
