Want to make the word in a answer bold, you can do that.
All you need to do is wrap the text you want to change with one of these codes.
[b] makes your font BOLD[/b]
[i] Makes your selection Italic [/i]
[u] Underlines your word[/u]
and remember you can get creative and use them inside your sentences for more impact and to draw attention.
This is going to make [b]bold[/b] stand out a lot more compared to [i]italic[/i] or [u]underline[/u]
