Hi Silke,
I did that for RC4 and I hope that it will work for RC5.
Here my changes:
In staff/tickets.inc.php AFTER (about line 380)
<th width="180" >From</th>
ADD
<th width="40">Status</th>
AFTER (about line 420)
<td nowrap><?=Format:($row,22,strpos($row,'@'))?> </td>
ADD
<td nowrap><?=$row?></td>
Good Luck..;)
Greetings,
Torben
