Do Bold Text in your message

[Ziggy Morgan]

you will see a Bold B in a square when your entering your text of your message, when you click it you will see two things show up, [ b ] & [ /b ], anything you but between these two symbols will show as bold text once you post your message.
 Or, if you highlight the text you want bold..then click on the Squared B above, it will automatically put the two symbols on each side for you creating the text to show up as bold when you post like THIS

Hope that helps!
