Hello.
My name is Brian. I usually edit the grammar and spelling in various wikipedia articles written in English, but I may sometimes reword sentences in articles that require attention, specifically in regards to grammar and overall cohesion. I try to make the articles readable for most, if not all, Wikipedia users/guests.
To me, both proper grammar and proper spelling are very important, and I believe it is imperative to understand how the English language and its constituents (reading and writing) function, and should behave.
