Welcom to the site and Welcome to the pain. I found myself in the same boat a year ago at this time. Things I had stashed away for years that I pulled out of a box I had to try and figure out. The parallels, well, those a nightmare in and of themselves. With that said congrats on the progreess, it's always one of the most dificult tasks to get through. If you look through the forum threads you'll a lot of people here you have gone through or are currently in the same dilemma.
With that said, utilize the knowledge and experince collectors here have. If come across something you just can't ID post a forum thread and someone here will know it. If you can't find where a card belongs, someone will know it's location already. If a checklist is missing someone will get it up in short order. The people on here are AWESOME and someone, okay many, are more than willing to lend a hand or solve a mystery.
Tired and trembling
I am descending,
will I have to stay here
and live this life again?
