It's going to be difficult for me to show how to do this because codes and tags are applied to text when constructing a post and then when the internet actually posts the message, the codes disappear and only the effects are shown.
Let's try the easy way first.
If you hit the POST button to create a post, you'll see buttons at the top of the new post. These buttons are:
B (which is the button for bolding words like this.)
I (which is the button for applying italics to words like this.)
U (which is the button for underlining words like this.)
If you would like to use one of these features for your words, follow these steps.
Example: Making a word bold.
1. type your post
2. use your mouse to highlight the word or words you want to be bold
3. when the words are highlighted, just click the B button and this adds the code for you in the area you have indicated. To you, in your post, it will look like this:

But after you post your message to the board, the tags will disappear and the text that was selected will be bold.
The same is used for the italics, underline and strikethrough buttons. Just highlight the words you want and hit the button for the effect you want to apply to those words.
The buttons add the code for you, but you don't have to use the buttons. You can add the tags yourself. It's easy. If you look at the example for bold, above, you'll see that all the button did was add brackets with the code in it. Just remember that there must be a set of left and right brackets at the beginning and the end of the words you want to use. Also remember, that a / shows where you want the code to end.
