Hi Amir,

I don't think it's easy at all.   I hope there are a lot of problems
and it will take time to check them.   Eventually the set will evolve
and people will discover that problems are cooked, have multiple
solutions or just plain wrong or unsuitable for various reasons.

Someone (probably Bob Hyatt) should be the "editor" of the set and
make the deletions as people find and report the bad problems.  There
should be a repository or simple way to get the latest version and at
some point we should pronounce it stable so it doesn't change forever!

Also we should give the problem set a name to distinguish it.

- Don
