2. How long does it take to update my stats on mining.bitcoin.cz website? I have been running this guiminer for more than 24 hours now and I saw one message on status bar of program which said something like "Shares: 1 accepted at 9:15PM" but I see that all my stats are 0 on the website.
With your speed 32KH/s you wont find many shares. If stratum difficulty is 1 then you will find share every 1 and half day
And Slush reward diminishes rapidly after few mins - it is best to use countinuous miner sending shares often.
