I had intended to keep this for friends only, but it has been requested more than once that I make it available so I suppose I should.
This is a userscript which makes it possible to make the level flair of users a rainbow.
Just for fun.
Where to get
How to use
When the script is running it will add a button to users’ user cards which says “Toggle Rainbow!”. Press this button to add or remove the rainbow flair from the user.
Furthermore you can change the colors of the rainbow by changing out, removing, or adding colors in the constant at the top of the script.
