When you're replaying/posting new, you'll be in a window for edit/typing [I don't know what this windows name

]
You'll see Code button, and click on Normal Mode.
Now type anything you want first.
Choose/highlight what word you want to be
bold/
color or
both. There's a button/pulldown menu you can choose. And then
Preview post.
If you don't like it, you can change by highlight that word, including the [/B] at beginning and ending or [color=xxx]
Try it, and you can also do with your signature
