I agree with what Mike just said, it's the best way and everyone can get involved.
It's been suggested to have an anonymous DS challenge but our experience has found that this quickly dies due to lack of interest.
It wasn't the administrative overheads that caused us to stop the anonymous terrestrial monthly challenge, it was lack of interest.
So we have reverted back to the requested method of the monthly challenge where everyone is welcome to post their own work.
Anyway it would be great to see this startup again, good luck with it, whoever is going to start it up again.
