actually this doesnt work right on the forums. causes a few errors. the one noticeable besides the problems when trying to use the auto refresh is it is causing some sort of issue when viewing a thread, you cant click on your user names and have the roll out options of viewing a users profile, sending a PM, so on. it conflicts in the showthread for some reason. that is another problem i have noticed about this mod.
i would suggest not installing this mod at all. use
