Okay, I was looking in the wrong place. It is a good idea to give us a path to the page you are viewing and a picture. It helps us out. Thanks.
You are looking for template "modify_profile".
Search the template for: (This is the block of code you are looking for.)
Code:
<legend>{vb:rawphrase instant_messaging}</legend>
Surround the block of code with either "<vb:comment> block of code </vb:comment>" tags or a conditional.
Code:
<vb:comment>
<fieldset class="blockrow">
<legend>{vb:rawphrase instant_messaging}</legend>
<ul class="group">
<li>
<label for="icq">{vb:rawphrase icq_number}:</label>
<input type="text" class="primary textbox" id="icq" name="icq" value="{vb:raw bbuserinfo.icq}" maxlength="30" dir="ltr" tabindex="1" />
</li>
<li>
<label for="aim">{vb:rawphrase aim_screen_name}:</label>
<input type="text" class="primary textbox" id="aim" name="aim" value="{vb:raw bbuserinfo.aim}" maxlength="30" dir="ltr" tabindex="1" />
</li>
<li>
