How do I change this??

[threat]

This is my site

http://www.gixxerplanet.com/home/index.php

The users online names are underlined, how can I take that off so their names are not underlined?

Thanks for the help and thanks for this great site

Give this a shot: Use a CSS markup for the usernames, and put "STYLE="text-decoration:none"" in the CSS tag.

So in your global CSS, something like:

.usermarkup
{
style:text-decoration:none;
}

And use for your opening usergroup markup:

<span class="usermarkup">

And for closing:

</span>
