Suggestions and Feedback

I was just wondering that there is so much good information on this forum that I would love to practice all of it.
Unfortunately time doesn't permit and often among the difficult question a few easy ones appear...

The GMAT timer is a good think to have...
I was just thinking that since its a user driven forum, why not let users rate the difficulty level of each question?
The levels could be like the ones below.

600 level
620-640 level
640-680 level
680-700 level
700-720 level
720-740 level
740+ level

Further more search criterias based on the question's difficulty level be there...

Also there be a search criteria where all questions with EXPERT comments could be searched.

A combination of the above two would be a "WOW" factor!! whatsay??

P.S. can there be guidelines that ppl don't post more than one question per post ?? unless its kind of discussion like the -ing versions discussion
