This is taken from another post:
How do I post a smilie ... can't find the icon ???
Go to settings--top right; then to general settings--scroll down list on left. Now scroll to Misc settings and check enhanced interface. See below----Make sure to save changes.
Miscellaneous Options
Message Editor Interface:
• Enhanced Interface - Full WYSIWYG Editing
• Basic Editor - A simple text box
• Standard Editor - Extra formatting controls
And I found that if you hit my profile top right, then your profile page comes up. On that page on right is a bar that says customize your profile. When you click that another page pops up for changing the color on your profile.
Have fun!
