How to customize user names

how can i customize a user name, like making it sparkle

Hi,

uzumaki chris

You can do it by adding this, but you alerady have it!

Code:

a[href="/u1"] {
    background: url("http://i35.tinypic.com/pxg87.gif") repeat scroll 0 0 transparent;
}

I've checked your forum, you already have it added, but you must remove this

Code:

a[href="/u1"] {
    background: url("http://images4.wikia.nocookie.net/__cb20100714204246/naruto/images/thumb/2/22/Mangeky%C5%8D_Sharingan_Madara.svg/18px-Mangeky%C5%8D_Sharingan_Madara.svg.png") no-repeat scroll left center transparent;
    padding-left: 13px;
}

You can't have to same rules with two same properties. That is why your sparkle is not displayed. Though there is a way to do both backgrounds not supported with all browsers.
