Sorry guys, I did not follow this thread for few days (Bitcointalk didn't send me a notification of new post to the thread update - that's strange).
I assume the correct conf file is "bullion.conf", because after I put the "connect" entries there, they made an effect.
Yes, I tried that and it worked.
Last few days I have installed temporarily nodes on two Linux servers, synced them from scratch, and will try to modify the source code a bit, to stake at least once... I assume the wallet doesn't stake, because it thinks it is not synced. So I want to forcefully set the "synced" status and see what it does... Lets see if this works, if not, I'll try to send the transaction as Timelord2067 suggested.
I'm now at block 3762216 which was received eleven minutes ago. My transaction has also been confirmed which can only mean that there just simply hasn't been any coins staked in the last two weeks.
UPDATE: well, it seems this indeed worked!

My wallet staked once, then some other wallets started staking, and the chain is moving ahead now! Now we need just two things: (1) enough stakers to move it further (I have just 12 inputs..); (2) somebody doing anything to revive not only the blockchain, but the coin itself...
My guess is that there were no transactions plus there were no coins being staked and, although every-one's block-chain had downloaded the entire block-chain the program though it hadn't been completely downloaded and was showing "Out of sync" - if that makes sence?
I'll try to keep my wallet open a bit more often from now on to help ensure there are coins staking.
