Few days back I had sent an email to ICC (International Cricket Council) proposing some changes. Today I got a reply from them. Hope they implement my suggestions.
I copied the email below.

Comments:
I propose 3 changes, which is sure to make the game of cricket more
interesting.

(1) Challenge : The teams should be allowed 2 challenges. When the
umpire gives a decision, which the team/coach feels is an incorrect
decision, they should be allowed to challenge the decision. And third
umpire should come into the picture.

(2) Distribute Field Restriction : One day matches has the field
restriction for the first 15 overs. I believe making the field
restriction more flexible, just say, make it 3 session of 5 overs each,
and the fielding team captain can choose when to apply each of the 3
sessions. This will definitely make the game more interesting by having
an additional strategy to think about.

(3) Timeout or Communication : The coach, should be able to communicate
with the team by timeouts, say 2 for each team, or should be able to be
in touch with the captain by wireless.

These 3 changes will definitely change the game for better and make it
more interesting.

Thanks
