Use all uppercase or all lowercase letters and the meaning is identical. Never use periods (dots) between your acronym letters; it would defeat the purpose of being a shortcut. For example, TTYL would never be T.T.Y.L. Recommended Etiquette for Web and Text Jargon When tempted to use an acronym, evaluate who your audience is. If you know someone well and it is a personal and informal communication, then absolutely use abbreviations. On the flip side, if you are just starting a friendship or professional relationship, avoid abbreviations until you've developed a rapport. If messaging in a professional context with someone at work, or with a customer or vendor outside your company, avoid abbreviations altogether. Spelling out full words shows professionalism and courtesy. It is much smarter to err on the side of being too professional at first, and then relax your communication over time organically.
