In an age of twitter lingo, texting, and autospell it can become all too easy to let your grammar and punctuation chops get rusty; fortunately, we have a few guides you can keep handy that will help you stay sharp.
The Punctuation Guide
This enormously useful guide (h/t LifeHacker.com) is stupid simple to use, all you need to do is click on a punctuation mark and learn all about it alongside a quick list of example uses.
The Oatmeal Grammar Guides
Technically, these are a mix of grammar and punctuation guides, but we won’t quibble over it. If you aren’t already familiar with Matthew Inman’s TheOatmeal.com, brace yourself for a quantum singularity strength time suck that you won’t regret for a single moment. You’ll never have a better time missing deadlines and getting an official warning letter in your HR file (seriously though, missing deadlines is bad so don’t do it).
If you’re more of a visual learner, this is the way to go; some of the most useful in the mix include How to use a semicolon; the most feared punctuation on earth, When to use i.e. in a sentence, and How and why to use whom in a sentence.
Although it has nothing to do with grammar or punctuation, Inman’s How A Web Design Goes Straight To Hell should be mandatory reading for any arts organization considering a website redesign.
