Monte, when you are on this page, the Forum, if you scroll to the top you will see a list of topics across the top. If you click on the second one from the left, "Search TIGHAR", it will take you to the page to find things. It has instructions, topics and a place to enter the subject you want to explore. When you finish, if you are not on the "Search TIGHAR" page, use your return arrow to get there, then go to the options at the top, click on Forum and you will return here.
I hope you are ready to do a lot of reading. Have fun!
