Suggestions and Feedback

I joined the site recently and did look at some of the available resources.
After I looked at a few notes, I was a bit disappointed. There is clearly plagiarism in these notes. I know these folks are sharing the notes out of good faith, but let's not steal content from others.

Example-
1. Rajat's SC notes and GMAT_Verbal_Notes_By_Sumit use same material in ---------

"You utter a sentence like this to your friend in GMATland:
"My sister, who just graduated from college, is coming to see me."
In GMATland, since your friend (we presume) knows you well and knows that you have only one sister, this extra bit of information is considered unnecessary to identify which sister it is you are talking about. It is a sort of "by the way" information--"My sister is coming to see me, and oh, by the way, she just graduated from college."

2. The GMAT notes by Sumit are similar in content and layout to Manhattan GMAT Prep.

My attempt is not a witch-hunt and I don't have time for this stuff, but found striking similarities. So please be honest in your noble cause.
