You probably noticed that Pyramid cluster was overloaded those last months.
As a result, it seems some problems were switched to cube cluster by admins.
It isn't without sad consequences ; just an example pointed by numerix.
With an answer from Mitch in comment in TWOSQRS problem:
I fully agree with those words.
The situation is probably unchangeable ; we'll have to compose with that.

Here is a place for spoj users to give their propositions.
My wish is to see those problem rising again.
Sadly some old destroyed ones could land in tutorial, and set again by original psetter, a new valuable psetter, psolver, or neutral admin.
Some problems could be destroyed without any solutions. (??? those rare ones will be able to go back to Pyramid ???)
As a first proposition, I vote for an adaptation the nearest possible to the original problem by one of the best psolver (or an association).
The test cases could be made by several such psetters, with a several heads engine.
When test cases checked, the problem could be set by a neutral admin, in order to let the new psetter play "the game",
and to not allow him to read others codes.
The "new-psetters" would be only credited in the end of description.

Hope you'll find some great ideas and promote your favorites ones.
Please be constructive. We all want the best for spoj.
