If you use LDM to create links to other parts of your forum, e.g. showthread.php?t=NN or ?p=PP to link to 
thread NN or post PP, you may want to fix showthread's navbar to refer to the LDM hierarchy rather 
than the normal forum/thread hierarchy.

To achieve this, upload the file rewrite.txt into your main forum directory, enable LDM's mod_rewrite 
setting and install the showthread-plugin.xml plugin. 

This catches situations where there is an additional catid=N parameter as part of the showthread.php
url. The showthread.php code does not expect this parameter and ignores it. The plugin spots the 
parameter, looks up the original link's details and substitutes an LDM-based navbar.
