Many of you will be happy to hear that it is now (once again) possible to exclude individual forums from appearing in the New Posts search results.
To exclude forums, visit the User CP -> Edit Settings page, and scroll to the bottom, where you will see the following:
Simply select the forums you wish to exclude from New Posts (hold down CTRL key to select multiple forums), and submit by pressing the Save Changes button.
This functionality was originally created for older versions of the forum software which powers PCF. The code has been tweaked in order to work here on PCF, so there may be some odd or unexpected behavior. Please report any such issues here in this thread and I will work on getting them sorted out.
