• How easy or difficult was it to find articles that needed editing? Were the errors you found factual or grammar / spelling

I moved to Canada from Kiev, Ukraine in 2000. My father worked in Chernobil Nuclear Power Station for many years after the radiation explosion in 1986. So I know what happened there, how it happened, how it was right after that disaster and how was it many years later.
The information I found on this topic was correct and I was very surprised to see that it was very much up to date.
English is not my first language. I would prefer not to do any comments on grammar or spelling of the articles I red.
