This weekend I'll be leaving the vBSEO add-on turned off for performance testing. vBSEO, amongst other things, is what gives us the nice looking URLs with the thread title in the URL instead of the thread ID number. EG: Instead of [noparse]http://www.coolscifi.com/forums/showthread.php?t=123[/noparse] you would see something like [noparse]http://www.coolscifi.com/forums/star_trek_movie[/noparse] in the browser. This means that any inbound links (links on other sites that link to Cool Sci-Fi) that are using the re-written URLs will not work this weekend! If the performance problems we've been having lately continue then vBSEO will be turned back on Sunday night but if the problems are relieved then we will leave vBSEO turned off permanently.
