I'm sure many of you will like this, I added a work around before to filter topics and posts in the Politics section however this is will allow you to filter posts and topics from any forum when you use the "New" or "Active" links.
Click this link to go to the page in the control panel:http://nepacrossroads.com/ucp.php?i=prefs&mode=search
-----or for future reference-----
First click the "User Control Panel" link
Click the "Preferences tab"
Click the "Edit Search Options" link on the left
Put a check next to any forum you want to filter topics from and hit submit. You can always change these preferences at any time.
