I've checked in here after a long absence and see things have changed. Have threads like The Rifleman Series and how to build an LTR, etc. been removed, or do you have to be a state member or whatever to see them?
Welcome back, Burke.
To answer your question, yes, many things have changed with the forum, and many changes are planned for the near future, as well.
Information on the Liberty Training Rifle can be found under the main heading "Rifle Knowledge Bank", found here:

I can't seem to locate "The Rifleman" series, though I am sure it is somewhere here on the forum... I'll see what I can come up with and get back to you.
Burke, if you'll PM me your email address, I can email you The Rifleman series. I have it in a .doc file.
