[App_rpt-users] Reading archives

I asked this question before and still haven't conquer this problem. I am trying to view the Gzip'd Text archives on the App_rpt-users Archives webpage at http://ohnosec.org/pipermail/app_rpt-users/. I have tried the instructions found at http://johnpoelstra.com/tag/import/ and it works for his example but when I apply the same instructions for the files of this group it doesn't produce anything I can read. When I download and unzip I get a .txt file but when I open it all I get is a bunch of box symbols It would be really useful to be able to search these locally all in one folder as opposed to browsing through each month one at a time. Any suggestions? Mike - N3KPU
