For those of you who DO NOT have the QUICK REPLY BOX, you will need to change your settings if you want to post pics, change your fonts, etc. GO HERE:
You have to change your settings... Go to SETTINGS, scroll down to GENERAL SETTINGS, then scroll down and click " Enhanced Interface - Full WYSIWYG Editing." This is what you need to use the QUICK REPLY box in posts or in PM's. At the top of this box you'll see icons where you can change your font, add a picture, etc., just mouse over the icon and it will guide you from there. So before you do anything make sure your settings are changed. Have fun!
