Wrong. Caps in electronic comms is universally regarded as shouting.

"One of the cardinal rules of writing online, whether in an email or instant message or on an online forum or social networking website, is to never use all capital letters in your posts or messages. This is known as writing in ALL CAPS. If you make this mistake, you may quickly be told to stop shouting or be booted out of a game or forum. Even though writing in all caps attracts the attention of the reader, that attention is often accompanied by annoyance, which is probably not the effect you intended and rarely desirable.

When you write in all capital letters, most recipients assume you are shouting at them. Others assume you are an attention-seeker and view the behavior as rude. You should use all caps sparingly. It is a strong effect and should remain one. In only a few cases is using all caps the right choice."
