I do a similar thing with conditionals to help promote the trader ratings but instead of just showing a user's score I also show a message at the top of each post indicating how "safe" the user is. This is accomplished with code in two places:
1) In the phpinclude_start template I have the code $classified_forumids = array(308,214,215,216,226,284,220,217,218,219,227, 223); which is an array of all our trader forums (it's easier to use an array then a if/and 10 conditional as you will see later on).
2) In the postbit/ potbig legacy template I have the following code right before <div>$post[message]</div>
Code:
<if condition="in_array($forum[forumid], $GLOBALS[classified_forumids])">
<if condition="$post[ratetradetotal] != 0">
<if condition="$post[ratetradetotal] < 0">
<div style="text-align:center;font-size:12px;color:red;font-weight:bold;">Negative: This user has <a href="/traderratings.php?$session[sessionurl]u=$post[userid]" style="color:red;">trader rating</a> of $post[ratetradetotal]!</div>
<else />
<div style="text-align:center;font-size:12px;color:blue;font-weight:bold;">Positive: This user has <a href="/traderratings.php?$session[sessionurl]u=$post[userid]" style="color:blue;">trader rating</a> of $post[ratetradetotal]!</div>
</if>
<else />
<div style="text-align:center;font-size:12px;color:green;font-weight:bold;">Neutral: This user has no <a href="/traderratings.php?$session[sessionurl]u=$post[userid]" style="color:green;">trader rating</a> history!</div>
</if>
<div style="text-align:center;font-size:12px;"><a href="/traderratings.php?u=$post[userid]&do=feedbacknew">Leave feedback for $post[username]</a></div><br />
</if>
Using this conditional set you could easily do just about anything from showing different information int he threads to just showing the rating in posts in certain forums (or both).
