As you may know, the forum search has been broken for more than a year now. Not being able to search the forums properly was bugging me. I hate the fact that knowledge from older topics was being lost, or people would keep asking the same thing repeatedly, because it wasn't possible to reliably find previous topics. A good case in point was not being able to find all the Wrye Bash threads.
To work around this, I collated a list of all 449 pages of topic headlines on this forum into a text file (inlcuding meta data like who started the topic, number of views and replies, etc). That comes to 13,464 topics, going back more than 5 years.
Simply load the file into a text editor or Excel, and search away. If you use a text editor like Notepad++, the URLs will be shown hyperlinked so after searching you can just double click the links to auto open them in your browser.
