My own comment is that our little corner of the internet is VERY important to many people, and it's history is worth retaining for current and future members.
Definitely, whilst a lot of the older posts may contain info that is now "common knowledge" for many older posters on the site or more experienced pin techs/restorers, I know for myself that searching thru and reading old topics is extremely valuable as someone relatively new to restorations and working on a pin in a more in-depth level. Pics that go with those old posts obviously help tremendously too.
