So you wanna put a playlist on your profile? Here's what you gotta do! ^_^

Go to www.skem9.com
Then make an account (it's completely free, as long as you don't download anything)
Put your songs on there!
When you're done, go to "post playlist" and find the Gaia Online code
Go to your profile and open a new media box by clicking "edit profile" and going to "contents" and making a new one (only works for current style)
Click "edit" on the media box
Paste the code in the box that pops up in the place where it says "URL"
Click "update"
Save your profile
Go to view
Now you have a playlist!!! ^_^

If you have any questions, post them in this forum! ^_^
