no - nothing wrong! But you can hit "forum home" after reading a thread to get back to the listing and that doesn't add a blank message at the end, or, if you wish to make a comment, then you can type it in and hit "submit message.

the "back" button on your browser will also get you back to your listing without adding blank messages.

Wasn't sure if you were deliberatly bringing the threads "up" or whether you were having trouble.

if you join as a member, you will get a "trace" function that will track threads you have an interest in, whether or not they have fallen off the main page.

Welcome to the MudCat. It is indeed a great resource.
