Habbo.. haha. I remember that. Hmm, wonder if I can still log in..
Yay I can lol
Code from habboremix.net
code:
<div id=loading style="
position:absolute;
cursor:hand;
top: 0;
left: 0;
width: 110%;
height: 2000;
z-index: 9000;
background-color: black;
-moz-opacity: .5;
opacity: .50;
filter: alpha(opacity=50);"><table width=100% height=600><tr valign=middle center=top><td valign=middle center=top><center><img src=http://www.habboremix.net/img/MFITV3LEIGS1CYU.gif><br/>
<font style="text-align: center;
font-weight: bold;
font-size: 12px;" color="#ffffff"><b>Please wait!</b></font></center></td></tr></table></div>
Obviously don't use that exact code. Change the image, etc. I'd also reccomend contacting them first before using the code.
