Hello guys,

I want to expose a "problem" that I think a good part of the members feels the same way. Why a member that successfully registered in a contest, read all problems and did nothing during the contest have his rating unchanged, however a "better" competitior decreases his rating doing a single problem?

I think it works similar to TopCoder system, you can register and not take part of the contest, however in topcoder you do not have a "unregister" option and if you open a problem, you are already participating.

A very simple solution: If you register, you are already participating.

Another approach would be insert a participate button or include the people who opened some problem.

Sorry for my English, but you got what I mean.
