<div style="font-family:Arial;">Thank you very much for your reply.<br></div>
<div style="font-family:Arial;">This is exactly what I wanted, and will employ, for problems that I code.<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">What can be done for problems that others have authored?<br></div>
<div style="font-family:Arial;"><br></div>

menu on the "colorful" editor. I would describe these as predefined conditionals so the postanswerdate pair, for example, will only display what is within the opening and closing tags after the answer has become available. If you put your link to a solution
PDF inside a pair of postanswerdate tags, that should do what you're looking for. The others work analogously I believe.<u></u><u></u></span></span><br></p><p><span class="font" style="font-family:Calibri"><span class="size" style="font-size:13pt"><u></u> <u></u></span></span><br></p><p><span class="font" style="font-family:Calibri"><span class="size" style="font-size:13pt"> <postanswerdate></<wbr>postanswerdate><u></u><u></u></span></span><br></p><p><span class="font" style="font-family:Calibri"><span class="size" style="font-size:13pt"> <preduedate></preduedate><u></u><u></u></span></span><br></p><p><span class="font" style="font-family:Calibri"><span class="size" style="font-size:13pt"> <solved></solved><u></u><u></u></span></span><br></p><p><span class="font" style="font-family:Calibri"><span class="size" style="font-size:13pt"> <notsolved></notsolved><u></u><u></u></span></span><br></p><p><span class="font" style="font-family:Calibri"><span class="size" style="font-size:13pt"><u></u> <u></u></span></span><br></p><p><span class="font" style="font-family:Calibri"><span class="size" style="font-size:13pt"><u></u> <u></u></span></span><br></p><div><p><span class="colour" style="color:black"><span class="font" style="font-family:Calibri"><u></u> <u></u></span></span><br></p><div><p><span class="colour" style="color:black"><span class="font" style="font-family:Calibri">Doug<u></u><u></u></span></span><br></p></div>
