slight article name changes break old URLs?
Just looking for some clarification really.
On my site with normal forums, showthread.php looks for a thread number. So say I have a URL for a thread, e.g., (home URL)/showthread.php/8886-My-First-Drive-Review. If the thread name gets changed from "My First Drive Review" to "First-Drive-Reviews", the new URL would be (home URL)/showthread.php/8886-First-Drive-Reviews, but the old URL still works since the thread number is the same. However, it seems like with showwiki.php, minor changes in the thread name totally break previous URLs. It that right? If so what was the reason for designing it that way?
