As a French Canadian, English is my second language. I'm using it all the time at work and on the Internet (obviously) but I'd like to learn to write it properly.
My goal is to be more fluent to be able to write articles for my websites in proper English - grammar and structure.
Is there any websites like Khan Academy but focused on languages lessons? I'm looking for something engaging and rewarding.
P.S : As a bonus if you have any websites or books on writing content with good flow and structure, I'm a taker!
