LINKS

The use of links in a posts is necessary.
For example:

• When we add a link, it's clickable automatically i.e. https://steemit.com/hive-172186/@humblesoul/achievement-3-by-humblesoul-task-content-etiquette

• But you can hide the link in a word, By doing the following syntax:
  [HERE IS MY ACHIEVEMENT 3 TASK](https://steemit.com/hive-172186/@humblesoul/achievement-3-by-humblesoul-task-content-etiquette will be seen as 👇
  HERE IS MY ACHIEVEMENT 3 TASK
