There's probably a few ways to do this but the easiest way would be to edit the welcome template and add div tags around the phrases then specify the font attribute for that div in the custom css section of the css manager.

Matter of fact, here you go.

CSS:

/* ***** styling for welcome headers ***** */
.welcomesize { font-size: 8pt; }

Template:

<if condition="THIS_SCRIPT != 'register' AND THIS_SCRIPT != 'login'">

<if condition="$show['guest']"> 
	<!-- guest welcome message --> 
	<br />
	<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
	<thead>
	<tr> 
		<td class="alt1">
		<div class="welcomesize"><phrase 1="faq.php?$session[sessionurl]" 2="register.php?$session[sessionurl]" 3="$vboptions[bbtitle]">$vbphrase[first_visit_message]</phrase></div>
		</td>
	</tr>
	</thead>
	</table>
	<!-- / guest welcome message -->
<else /> 

<if condition="is_member_of($bbuserinfo, 3)">
	<!-- / unconfirmed user message -->
	<br />
	<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
	<thead>
	<tr> 
		<td class="alt1">
			<div class="welcomesize"><phrase 1="$vboptions[bbtitle]">$vbphrase[welcome_unconfirmed]</phrase></div>
		</td>
	</tr> 
	</thead>
	</table>
	<!-- / unconfirmed user message -->
<else />

<if condition="$bbuserinfo[posts]<1">
	<!-- never posted message -->
	<br />
	<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
	<thead>
	<tr>
		<td class="alt1">
			<div class="welcomesize"><phrase 1="$bbuserinfo[username]" 2="$vboptions[bbtitle]">$vbphrase[welcome_neverposted]</phrase></div>
		</td>
	</tr>
	</thead>
	</table>  
	<!-- / never posted message -->
<else /> 

<if condition="$headerstime - 1209600 > $bbuserinfo[lastpost]">
	<!-- never posted message -->
	<br /> 
	<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center"> 
	<thead>
	<tr> 
		<td class="alt1">
