Can someone explain how Staking works.
Will i receive interest if for the past 3 days my Stake was "Stake=0.0" ?
Why it stays 0 all the time i dont get, is that important?

Sorry i just edited my post ,was my mistake for sending the last grc digit:)

BTW does exchange works or what is this guy talking about:
https://cryptocointalk.com/topic/1331-new-coin-launch-announcement-grc-gridcoin/page-316

aceypilot :"I was told the payment server is hung-up, and Rob will repair it when he has a chance. "

Ok now when i used only
addnode=node.gridcoin.us ONLY
i was able to sync but only with my 4th winxp computer
But this should be enough to exchange two wallets i have (i will copy wallet.dat to the client that is working)
Now when i try to use this page:
http://pool.gridcoin.us/CoinExchange.aspx
I did everything correctly and got green message but  then when i send 73.0339 grc from old classic wallet
it says "insufficient funds"
That is my second wallet thas only has the fraction of grc ,so is there a minimum i can exchange?
Also i thought it would be a good thing for testing purposes to firstly exchange only a small amount.

EDIT
************************
O yeah i cant send the very last digit, probably due to the transaction cost (did that same mistake few months back)

Not sure if i understand you.
How do i exchange the old GRC if i dont have old classic client up and running?

Nope nothing works.
I just installed classic client on third system  and i am even able to get "synchronizing with network" message
but its just gets stuck. And i have 1 active connection on that signal icon.
What is going on? 10 days ago i was able to sync and now when i have to exchange the grc nothing works?

I cant sync up the old classic wallets.
Tried it on two computers.
i also tried this config file:

rpcuser=username
rpcpassword=password
rpcallowip=127.0.0.1
server=1
daemon=1
rpcport=9334
listen=1
UpdatingLeaderboard=false
CPUMessage=Notified
suppressminingconsole=true
CPUMessage2=Notified
addnode=137.116.167.42
addnode=137.116.167.52
addnode=191.238.60.17
addnode=191.238.51.28
addnode=191.235.137.239
addnode=191.235.138.12
addnode=23.97.147.78
addnode=23.97.148.49
addnode=138.91.246.228
addnode=138.91.247.22
addnode=node.gridcoin.us
poolmining=false
cpumining=false
gpumining=false
suppressupgrade=true


It just gives me No block source available
I tried the new research client and it works and syncs up correctly.
Now i dont know how to exchange the coins, if old classic clients cant get synced then i cant send grc ,right?
