In the code of:
survey.php, question.php and group.php I found several occurrences of the following expression:

echo "<center><font color='red' size='2'>".$clang->gT("This survey is not currently active. You will not be able to save your responses.")."</font></center>\n";

In order to make the division between code and presentation optimal, I think it would be better to change this to the following:

echo "<div id='surveynotactive'>".$clang->gT("This survey is not currently active. You will not be able to save your responses.")."</div>\n";

All design issues can then be dealt with in the css file. This gives the designer much more freedom. I have not checked yet, but I suspect that in more cases design statements may appear in the code. Time for a cleanup?
