simply find:

<script type="text/javascript"> vbmenu_register("postmenu_$post[postid]", true); </script>

and now it depends on which postbit you use.
for postbit legacy:
find:

<div id="postmenu_$post[postid]">
				<a class="bigusername" href="member.php?$session[sessionurl]u=$post[userid]">$post[musername]</a>

after href="member.php?$session[sessionurl]u=$post[userid]" add:

style="text-decoration: none;"

for the regular vb3 postbit:
find:

				<div id="postmenu_$post[postid]">
					<if condition="$show['profile']">
					<a style="font-size:14pt" href="member.php?$session[sessionurl]u=$post[userid]">$post[musername]</a>
					$post[onlinestatus]
					<script type="text/javascript"> vbmenu_register("postmenu_$post[postid]", true); </script>
					<else />
					$post[musername]
					</if>
				</div>

after href="member.php?$session[sessionurl]u=$post[userid]" add:

style="text-decoration: none;"

and thats for vb3
if your inquering about vb2 than you'll just find $post[username] and add <div style="text-decoration: none;"></div> around $post[username]
