Thanks guys.

Which firefox version were you using?

firefox kept locking up my mac

there are a lot of little things it does that i like

I can also confirm this scroll bar shiznay, seems to be a webkit issue in the CSS.

Other browsers do not exist in my mind.

Haha, I wonder if the developers tested in, say, 1280x768 and 1440x900 and said "Hey, looks good with these settings! Other resolutions do not exist in my mind."

Just kidding around

Also, it might be interesting to note that at higher resolutions (i'm at 1440x900) there's a lot of "white" (black) space over to the right, which wouldn't be an issue at all except there's a horizontal scroll bar on my screen even though all the content fits nicely in my window.

This is in Chrome, haven't tested other browsers because I never use other browsers.

Yeah, and wut. I like viewing my 24 incher in such a resolution. 

Anyway, most sites should be able to be viewed at such resolution. Fairly average.

It's a CSS issue and since I'm in a good mood (and pretty anal) here's the fix:

before:

#forum_welcome {
    width: 68.5em;
    font-size: 1.4em;
    line-height:1.9em;
    padding: 2em 4em;
    border: 1px solid #111;
    background:#111 url(/forums/style/Default/images/default_userpic.gif);
    color: #fff;
    border-radius: 4px;
    margin-bottom: 1em;
    -webkit-border-radius: 10px;
    -moz-border-radius: 10px;    
}

after:

#forum_welcome {
   padding: 2em 2em 2em 2em;
   font-size: 1.4em;    
   line-height:1.9em;  
   border: 1px solid #111;    
   background:#111 url(/forums/style/Default/images/default_userpic.gif);     color: #fff;    
   border-radius: 4px;    
   -webkit-border-radius: 10px;   
   -moz-border-radius: 10px;     
   margin: 0 200px 1em 0;
   display:block;
   position:relative;
   }

removes width, changes padding, changes margin and adds: display:block;
   position:relative; etc etc

Next:

before:

#forum_welcome a {
    display: block;
    background: #c6076c;
    border: none;
    width: 12.3em;
    text-transform:uppercase;
    text-decoration:none;
    border-radius: 2px;
    -webkit-border-radius: 2px;
    -moz-border-radius: 2px;
    padding:.5em 0 .5em 3em;
    margin: 0;
    color: #fff;
    font-family:sans-serif;
    font-size:.8em;
    font-weight:bold;
    cursor:pointer;
    margin-top: 2em;
    margin-left: 35em;
}

after:

#forum_welcome a {
    display: block;
    background: #c6076c;
    border: none;
    width: 12.3em;
    text-transform:uppercase;
    text-decoration:none;
    border-radius: 2px;
    -webkit-border-radius: 2px;
    -moz-border-radius: 2px;
    padding:.5em 0 .5em 3em;
    color: #fff;
    font-family:sans-serif;
    font-size:.8em;
    font-weight:bold;
    cursor:pointer;
    margin-top: 2em;
    margin:auto;
}

Removing both the margin:0 and the very poor attempt at centering with margin-left:35em; In turn placing margin: auto to replace both and thus centers exactly, rather than half ass

Also, I'd null out:

  padding-left: 4em;
  padding-right: 4em;

from:

#forum_welcome p {
    margin-bottom: 1em;
    padding-left: 4em;
    padding-right: 4em;
}

leaving simply:

#forum_welcome p {
margin-bottom: 1em;
}

Simply for aesthetic reasons... to each their own, I guess.

Tested in Safari and Firefox... and if it works in Safari it more than likely works in Chrome.

Other browsers do not exist in my mind.

Should look like this now in a 1024x768 screen, after fix, of course:

Tada. That bit should now be 100% fluid, I believe, rather than fix width.

Ok, I think that should do it.

Cheers m8! xD
