No problem, I am happy to hear that it is back up and running; I just checked 4 of my old addresses and already 1 of them is giving me a positive message -
"We can dig this address! Fill in your private key and payment info, and we'll send your coins to you."
Congrats first off

I am wondering if there is anyway to receive any indication of how much coin I will be receiving before disclosing my private key? I'd like to know if it's "worth" it, even though it is empty if I am compromising one of my addresses for next to nothing then I won't bother.
Right now our system doesn't display the qualifications of the address... just the fact that the address does, in fact, qualify for at least one of the forks we dig for.
The prices on the front page of our digger are just rough estimates. The actual payment sent for your address is the actual coins earned from the market liquidation.
I have dozens more addresses to check, but I want to make sure the one address works. I am excited to dig through my old wallets, I could use the money and it seems like I already am sitting on some.
There is a chance you are sitting on a nice chunk of hidden coinage.
Here are the dates to remember:
May 12, 2014
August 1, 2017
October 24, 2017
Each date will qualify your address for additional coins.
