If you're a writer, and I certainly hope you are even if it's only your diary, you should check out this awesome website. I have nothing but great things to say about it. It's Daily Writing Tips. It's a great daily resource into the world of writing faux-pas, grammar, and 'who knew?!'
If you visit the site, you'll see that there's an entire list of "popular articles" on the right and a list of categories on the left. There probably isn't any topic too small or too "niched" to have been dealt with before. So, click on the link above or copy and paste the link below... either way, check this site out. Also worthy of note is that you can publish it to your RSS feed and have it go directly to your blogger dashboard. It's a mighty handy little trick!
