Should I lowercase email addresses?
Usually, yes. Email domains are case-insensitive and almost all providers treat the whole address that way, so lowercasing helps find duplicates.
How do I capitalize the first letter of sentences again?
Use Sentence case, which lowercases text and capitalizes the start of each sentence.
Is my text uploaded anywhere?
