Go to the top of the Forum page. There, you will see a lot of keywords in red and blue type.
Look for the keywords, "HTML Sandbox" on the bottom row.
Open the HTML Sandbox and read instructions on how to post photos, use color or different type sizes, and other handy hints.
You can practice posting photos and playing with typography on the HTML Sandbox thread without getting flamed.
Great. Thank you very much. I know I’ll definitely need to practice.
