Hi @omor.osama,
Similarly to what I mentioned to @Morichi above, the email your mentor has registered with should have received an email (or even two) already. If that’s not the case, please let me know and I’ll try my best to sort it out right away 
You are very much right – they are way better at organizing things than we are. Hopefully, we’ll still make it and the whole thing will end up being quite a bit of fun
If you’d like to help out, we could use all the help we can get, especially around thinking about remote-enabled Technical Challenges: Call for Suggestions: Technical Challenges - #2 by Armin
Hope this helps!
