P.S. What is wrong with you guys? Accusing me of scaming. Casually requesting me to send you 25btc. Promoting your own pools. From my perspective this doesn't look like a welcoming community.
Quite simple. New user account. Take a look at the Nexious pool thread
https://bitcointalk.org/index.php?topic=1135806.0 to see how responsive that new pool was. Eager to get people mining at his pool, bending over backwards with support and incentives to people to mine there....then once the block was found, he was never seen or heard from again.
And simply put, the request for you to send over 25 btc is to escrow it in case your pool DOES find a block and you won't take off but pay out the people who spent their money and effort to get that block. All those people were cheated and it makes us all leery of new pools popping up.
