Correcting Errors or Score Board

Ok, I received some comments about the invitation mail, It was great. Those comments remember me that I have to be more carefull with the times and some conexions. Thinking about it, I decided that maybe could be amusing if that comments receive some score. I think in someting like the Acrónimos's score system. Here the rules:

• Each comment have a point
• The first observation have the entire poit, if you comment something that someone already comment too, you have half point
• You never lost points

I tougth about this because in some way this excersise could be ilustrative (and fun) for all the participants...

Now, my errors:

When I write	I should write
for practice	to practice or for practicing
I want that if you can/may help me to improve my profiency in this language	I want you, if you can, to help me improve or I'd like you to help me improve my second language
I count with you	I count on you
be luck	good luck or my best wishes

Thanks a lot for your comments and suggestions.
