I chose this link because it is reliable and it is for both grammar and writing. The website title is Guide to Grammar and Writing, it provides you with all grammar and writing issues, and on top of that, it exceeds its usage. This website contains links and recommendations of other websites and colleges for grammar and writing problems. The main reason Charles Darling(founder of the Guide for Grammar and writing) created this guide, is so that students could have help writing research papers and reports and students could look up grammatical issue on their own. This website provides a list of grammar mistakes so that one can understand what to use in creating a paper. There is a list of extra resources on the website such as: an annotated bookshelf, that recommend different sources; quotes that are from authors that speak about writing; samples of different types of business letters, memos, and application letters; it has a section that can be use with PowerPoint to retain more information; and it has where you can take quizzes on a number of different grammar issues. I believe that this is the best source that one can use for any kind of writing issue.
