When addressing the issue of all capitals in online forms, it is important to know that the rules are not universal. Some online forms may ask specifically for responses in all capitals, for reasons that will be discussed later. In general, however, the practice of using all capitals in online communications is discouraged for both technical and social reasons, such as readability and the perceptions of the recipient. Certain online forms may also be case-sensitive, which means any capitals typed during the creation of a password or email address must remain capitals later.
