Hi and welcome to Pet Talk! I own two budgie birds named Rocket & Sky and a sheltie named Mickey.

To make text bold, underlined, italic, or colored all you need to do is click the buttons at the top or type in

for bold: [b] yourtext [/ b]
for italics: [i] your text [/ i]
for underline: [u] yourtext [/ u]
for color: if you want it blue: [color=blue] yourtext [/ color]

No spaces.

Hope that helped.
