A Game a Day (http://www.agameaday.com)
Every day, a new word game, quiz, or
puzzle will challenge your spelling, grammar, rhyming, and vocabulary skills.

Grammarcheck
An online grammar check can come in handy for anyone who wants to write proper English.
Like many, you probably learned many of the grammar rules all throughout your school years.
Also, like many, you’ve likely forgotten much of what you learned. Where does the comma go, for instance?
Is ending your sentences with a proposition really that bad a practice?
Are there hard and fast rules for when to use who, that or which?
All of these questions, as well as many more, can plague both amateur and professional writers.
Doing a grammar and spell check helps to settle these questions and give you more confidence in your writing.
