Hello.
The board's software offers a wide range of formatting tools, quite like a text program like Word or others.
As Csar said, it works by highlighting the bit of the text that you want to change. I suggest you either use the function "Quote" or "Reply" to use them. "Quick reply" offers only limited options.
From left to right, bottom row of my screenshot:
Bold, Italics, Underlined,
left aligned
centered
right aligned
- Numbered
next 2: Indent selected text to left or right (this is right)
Add a link
The next one allows you to remove the link again.
Email-link
insert image: 
That should be sufficient.
The others are secret magic tools.
I suggest you just try them...
Try to quote my answer and you'll see my formatting.
Hope that helps.
R'as
