Final answer:
When changing a message from informal to formal, it is important to omit slang, avoid technological aids, and not add colloquial language.
Step-by-step explanation:
When changing a message from informal to formal, one important consideration is to omit slang. Formal communication requires the use of standard and appropriate language, and slang can be seen as unprofessional or disrespectful. Another important adaptation is to avoid technological aids, as formal messages are typically conveyed through traditional and more formal means such as emails or letters. Lastly, adding colloquial language should be avoided when changing a message to formal, as colloquial expressions are more informal and may not be suitable in a formal context.
