Hi Laura,
In the Frequently Asked Questions section, there is a section that teaches you how to do color, formatting, etc. See:
FAQs Section - Click HERE
Basically, you just need to put brackets [], around the letter "I" to make italic text. Then close the tag by doing a:
[/I]
to make it stop. I would show you an example, but if I type the code, it will not display the code, it will display the results of the code (if that makes any sense).
The FAQs will answer your questions.
AOE,
Jen
