Hi @kus-knee!
I hope you are well and still in Greece :)
I am sorry for the off-topic comment, but since we discussed about it a couple of days back, I am here to show a very new app regarding contests.
You can find the introduction post here and apparently the project owner is still actively updating (I have seen a recent update 11 days ago)
I hope it will be useful for you!
Wish you the best and just a fyi ..
I have suggested Crete as a destination to the Organizer (one of the high hierarchy ones :P) for the next decentralized! (He seemed to like the idea!)
All the best!
Katerina
