I'm very happy to announce that the who Install/Uninstall has been added to the forums. Most of you are already aware how this works. For those who don't know. Let me explain.
If you see a hack that you like, and you have decided to install that hack on your forums, then you should click the install button which looks like this.

. If you have uninstalled that hack for any reason that you should click on the uninstall button. Which looks like this

.
You may see who installed the hack by clicking the numbers on the fourmsdisplay. It will show the number of people who have installed that particular hack, the user names, and when they installed it.
So if you have installed a hack i would suggest clicking the install button, because who wants to post a support question in a hack-thread and don't have as installed in postbit.

Have fun and happy hacking!
