yes it is.
i think it is a very good idea,because here are challenges,only the creator has solved.
or other ones only 2 or 3 people has solved.
i think the challenges which only has 1 -2 people has solved could be deleted.
but i know erik, has not much time .
they are to hard.
my challenge was hard too and nobody could solve it. so i have made a new challenge for the people.
i think this is much better.

but this is not the fact in this thread.
i think we can create two areas for the people.
this makes more fun i think.
many challenges are very hard.but this is erik's or tbs's decision what to do.

hehe. there are some cryptos you haven't solved, ehh? You would be happy if erik delete all of them... lol

Corso,
there are many cryptos you havent solved

yes, but i dont want to delete those that i haven't solved.

what do you want with them,when nobody could solve them? 0_O
Caesum or TheHiveMind cant solve them,so what do you want with those challenges!?

Does it automatically mean if TheHiveMind or Caesum can't solve a challenge, it's unsolvable?

CyBeR ¬¬....

no,they arent all unsolveable.but inferno knows Hive and Caesum.
the same on other sites.most time,is caesum one of the best and could solve most.
but here are some challenges so long uploaded and nobody has it
so......
