I added a little something to Step 6:

				<if condition="$post['fieldX']">
				<tr>
					<td>
						onXiam:<br />
						<a href="http://www.onxiam.com/people/$post[fieldX]" target="_blank">http://www.onxiam.com/people/$post[fieldX]</a>
					</td>
				</tr>
				</if>

Just made it look like it fit better to me in that location by adding this: http://www.onxiam.com/people/$post[fieldX] to the code.

Alternatively, I can see this being added to the IM fieldset as something like this:

			<if condition="$show['hasimicons']">
			<fieldset class="fieldset">
				<legend>$vbphrase[instant_messaging]</legend>
				<table cellpadding="0" cellspacing="$stylevar[formspacer]" border="0">
				<if condition="$show['textimicons']">
					<if condition="$userinfo['showicq']">
					<tr>
						<td>$vbphrase[icq]</td>
						<td>$userinfo[icq]</td>
					</tr>
					</if>
					<if condition="$userinfo['showaim']">
					<tr>
						<td>$vbphrase[aim]</td>
						<td>$userinfo[aim]</td>
					</tr>
					</if>
					<if condition="$userinfo['showmsn']">
					<tr>
						<td>$vbphrase[msn]</td>
						<td>$userinfo[msn]</td>
					</tr>
					</if>
					<if condition="$userinfo['showyahoo']">
					<tr>
						<td>$vbphrase[yahoo]</td>
						<td>$userinfo[yahoo]</td>
					</tr>
					</if>
					<if condition="$userinfo['skype']">
					<tr>
						<td>$vbphrase[skype]</td>
						<td>$userinfo[skype]</td>
					</tr>
					</if>
					<if condition="$post['fieldX']">
					<tr>
						<td>onXiam</td>
						<td>$post[fieldX]</td>
					</tr>
					</if>
				<else />
					<if condition="$userinfo['showicq']">
					<tr>
						<td>$userinfo[icqicon]</td>
						<td><a href="#" dir="ltr" onclick="imwindow('icq', '$userinfo[userid]', 500, 450); return false;">$userinfo[icq]</a></td>
					</tr>
					</if>
					<if condition="$userinfo['showaim']">
					<tr>
						<td>$userinfo[aimicon]</td>
						<td><a href="#" dir="ltr" onclick="imwindow('aim', '$userinfo[userid]', 400, 200); return false;">$userinfo[aim]</a></td>
					</tr>
					</if>
					<if condition="$userinfo['showmsn']">
					<tr>
						<td>$userinfo[msnicon]</td>
						<td><a href="#" dir="ltr" onclick="imwindow('msn', '$userinfo[userid]', 400, 200); return false;">$userinfo[msn]</a></td>
					</tr>
					</if>
					<if condition="$userinfo['showyahoo']">
					<tr>
						<td>$userinfo[yahooicon]</td>
						<td><a href="#" dir="ltr" onclick="imwindow('yahoo', '$userinfo[userid]', 400, 200); return false;">$userinfo[yahoo]</a></td>
					</tr>
					</if>
					<if condition="$userinfo['showskype']">
					<tr>
						<td>$userinfo[skypeicon]</td>
						<td><a href="#" dir="ltr" onclick="imwindow('skype', '$userinfo[userid]', 400, 285); return false;">$userinfo[skype]</a></td>
					</tr>
					</if>
					<if condition="$post['fieldX']">
					<tr>
						<td><img src="$stylevar[imgdir_misc]/onxiam.gif"></td>
						<td><a href="http://www.onxiam.com/people/$post[fieldX]" target="_blank">$post[fieldX]</a></td>
					</tr>
					</if>
				</if>
				</table>
			</fieldset>
			</if>

Replace fieldX with your correct field number.
