No your computer has not been hacked You are viewing the new PF 3.5 style! This style is purely aesthetic with virtually no new functionality. However we feel it does offer a more modern and productive experience at PF. Big thanks to the entire staff, SA's and HH's as they were a big help in final refinement (so blame them for anything you don't like ). Speaking of refinement, we welcome any feedback and suggestions. However, please keep in mind we have thousands of members and millions of visitors. It is impossible to please everyone. If there is a serious criticism, all I ask if that you give the style a few days to sink in. For better or worse, change is never easy. You might notice a few things missing. Please give me a few days to complete the transition, there are a few things I couldn't add or tweak until it was released to the public. There is one exciting new feature at PF and that is the Image Gallery. Located in the "Features" drop down in the upper nav bar. This image gallery displays all the images we have stored as attachments here at PF. You maybe simply browse the current images or search by file name keywords. You may also browse by forum by selecting the forum you want in the drop down menu and leave the search box empty. Then click search and you'll see images for just that forum.

If you are intent on using IE, make sure it is IE10 (IE9 is minimum).
