As you can see from my sig, there is a huge gap between the post and the actual sig-ness. I have no idea how that happened.
The only change between this sig and the last one is that I added some tables.
I realise that this may be a very hard question to answer without a closer look at the html behind it, so, here it is:

<table>
<tr>
<td>
</td>
<td>[b ]Wolfe[/b ]
AIM: WolfeFuzze
Funds: $10,000
</td>
</tr>
<tr> <td>[IMG ]http://img77.photobucket.com/albums/v234/WolfeFuzze/Wolfes_Wolf.gif[/IMG ]
</td>
<td>[b ]Hobbling Bob[/b ]: [i ]Command Wolf - Irvine Custom[/i ]
--Mods: None
--W/L/D: 0/0/0
</td>
</tr>
<tr>
<td>[IMG ]http://img77.photobucket.com/albums/v234/WolfeFuzze/b-rev-raptor2.gif[/IMG ]
</td>
<td>[b ]Mad Morris, the Eyeball Eating Maniac of Quirm[/b ]: [i ]Rev Raptor[/i ]
--Mods: None
--W/L/D: 0/0/0
</td>
</tr>
<tr>
<td>
</td>
<td>
Total W/L/D: 0/0/0
</td>
</tr>
</table>

Sorry 'bout that. Any help would be appreciated.

You need to add new <td> and <tr> tags for each new line. I also mash all the code together and it doesn't cause any problems.

My Sig Code:

<table border=0></td></tr><tr><td rowspan=20><img src='http://img29.photobucket.com/albums/v86/doctauros/steelhorizonsig.jpg' border='0' alt='user posted image' /></td></tr><tr><td><span style='color:gray'><b>Name -</b> Ben Slate</span> </td></tr> <tr><td><span style='color:gray'><b>Theme -</b> Irish Blood, English Heart - Morrissey</span></td></tr> <tr><td><span style='color:gray'><b>AIM -</b> finalcaliber</span> <tr><td><span style='color:gray'><b>Team -</b> None</span></td></tr><tr><td><span style='color:gray'>$10,000</span>
</td></tr> <tr><td><span style='color:gray'><b>Gojulas - </b>Imperius - No Mods</span></td></tr> <tr><td><span style='color:gray'><i>Status -</i> Ready to Rock</span></td></tr>
<tr><td><span style='color:gray'><b>Gun Sniper - </b>Longbow - No Mods</span></td></tr><tr><td><span style='color:gray'><i>Status -</i> Arena</span></td></tr> <tr><td><span style='color:gray'><b>Record -</b> 0/0/0</span></td></tr> <tr><td><span style='color:gray'> <img src="http://img29.photobucket.com/albums/v86/doctauros/Gareth-Aetholuss-second-org.gif"></span></td></tr></table>

No idea why, but removing all of the returns between the code did the job. Thanks for the help!
