Grammar and spelling police here. Just wondering if you'd like errors pointed out so you can correct them. Allowing grammar and spelling errors in training materials, especially those offered online, makes Box seem unprofessional and shady -- like a phishing email or letter from an online lottery telling me I've won money. I've found five errors on just the first page of the Get the apps you need lesson, and they're not British v. American English differences.
Happy to send screenshots.
